List of known CoD MW2 Errors, solutions & workarounds


- Be sure that your PC meets these system requirements:

OS: Microsoft Windows XP, Windows Vista and Windows 7 (Windows 95/98/ME/2000 are unsupported)
Processor: Intel Pentium 4 3.2 GHz or AMD Athlon 64 3200+ processor or better supported

Hard Drive: 12GB of free hard drive space
Sound: 100% DirectX 9.0c compatible sound card
Internet: Broadband connection required for Multiplayer Connectivity. Internet Connection required for activation

An Error can have more than one cause.

So it is trial and Error till you find what works for you.


1. Modern warfare 2 - Connection failed ( or installation problems ).

Solution : Go to Network connections on your PC > Right mouse click on your connection .

Go to the last tab; Windows Firewall >>> add the following ports :

1500
3005
3101
28960
Set them all on UDP and reboot PC.
Same goes for routers. Open up, Port forward. ( portforward.com - info for most routers and how to)

Call of Duty: Modern Warfare 2 transmits and receives network traffic on :

ports UDP: 1500, 3005, 3101, 28960 and TCP: 27015 (SRCDS Rcon port).

Additionally the Steam client transmits and receives network traffic on :

ports UDP: 27000-27015, 27015-27030 and TCP: 27014-27050.



*

Sometimes just a simple "Take the power plug from router out and put it back in" does the trick.
*

Switch of any anti virus program.
*

You use Norton ? Uninstall may help.

and just make a Backup from the folder named “players”. That is the whole savegame from the Singleplayer.

or
21. Vista / Windows 7: How to get multiplayer rank back after crash ?

If your running Windows Vista or Windows 7 and have not backed up your players directory you may still be able to recover it.

1. Browse to -- C:|Program Files|Steam|steamapps|common|call of duty modern warfare 2 or for 64bit Windows -- C:|Program Files (x86)Steam|steamapps|common|call of duty modern warfare 2
2. Right Click on the "players" directory and click propeties.
3. Click the "Previous Versions" tab
4. If you have previous Versions listed then your in luck.
5. Copy the "players" folder to "Players - Old" so that you have a backup.
6. Delete the contents of the existing "players" folder and copy the files from previous Version back in to the dir.
7. Restart MW2.

22. Technical support says about Back-Up :

1. Go to the Steam folder and find the Modern Warfare 2 install folder
2. Default location: C: |Program Files | Steam | Steamapps | common | call of duty modern warfare 2 |
3. Open the | players | folder
4. The multiplayer profile is updated regularly as a. Stat file and also includes a backup file.
5. All original profile files begin with md202ef8d and backup files will begin with md202ef8d.bak
6. Locate the profile and backup. Stat files with the most recent "Date Modified" listed in Windows
7. Move the profile. Stat file to a new location (Creating a new folder and placing it here should be fine)
8. Rename the backup. Stat file and remove the ". Bak" from the filename
9. Launch Steam and re-test this game.

23. Some think Modern Warfare 2 Single Player (and MP) has a Memory Leak Bug....

And changing the advanced graphic options from Extra to High fixes the "always on same point" crashes in MW2 Single Player.
There is a mistake in the coding for the higher setting that causes the leak and it doesn't appear to be present in the lower settings.

24. MW2 WIN_DIRECTX_INIT_BODY - "DirectX encountered an unrecoverable Error."

1. Right click on the desktop and choose "Preferences"
2. Select the "Options" tab
3. Click on the "Advanced" button
4. Choose the "Troubleshooting" tab
5. Lower the "Hardware acceleration" bar to "None"
6. Untick the selection box for "Activate combine writing"
7. Press "OK" and restart the computer

What the process is doing after this; is that DXDIAG is setting the DXDIAG settings to null.
Now do the same process again as told above, all the 7 steps.

When you have restarted the computer for the second time, now you shouldn't have any problems.
25. It appears that Modern Warfare 2 did not quit properly the last time it ran. Do you want to run the game in safe mode?

1. Single player is working ok.
2. But Multi-player does not work;

* Example : MW2 MP starts, shows the splash screen then the screen goes black and then nothing... MW2 hangs and you have to press ctrl, alt and del to start Taskmanager and end the no longer responding iw4mp.exe.
* So you start MP MW2 again and get the option for play in safe mode ? and you´re back where you started; MP doesnt work.

3. You remove game content through Steam and re-download or restore from backup BUT Multi-player still does not work !

Next bit seems to be similar as the above but there is a slight difference and it can get the MP back working.
Follow exactly what is written !

In Steam, select "Backup game files" for Modern Warfare 2 and Multi-player, (select both titles in the backup list). Then select Delete local content (verry important) for both single player and multi player.

Next, locate your Steam common folder, eg; D:|Steam|steamapps|common. There should be a folder called "call of duty modern warfare 2" .

You can delete this folder OR you may wish to move this folder to another location like your desktop.

Then restore modern warfare from the backup you made earlier and allow it to update and resync

Lastly, start multi-player as normal ... you may get a message "completing installation"... just retry and it should start up allowing you to set key bindings etc.
26. Connecting to IWnet problem - WORKAROUND SOLUTION

Start the CoD Multiplayer and try to connect.
While the game attempts to connect start the singleplayer of CoD (let the MP run in Background)and try to login into the co-op campaign. This will now work.You can now close the MP mode an start to play the coop campaign.

When you want to play Multiplayer just do it the other way around, start the Singleplayer,switch to spec ops try to connect ( click on two player mode) , then start the multiplayer(GO TO WINDOWS AND RUN THE SH.T) and you can now log in. ( search the games before u quit the single player.exe otherwise sometimes iT doesn't find the games ) ( if that all doesnt work try second time )

Worked for many.
27. Text / Graphic problems MW2

To all With a ATI MOBILITY RADEON X1600 (i think it works with msot of X1xxx)

Download this Drivers/Application:

WINDOWS 7
(SORRY CANT POST OUTSIDE LINKS)

WINDOWS XP
(SORRY CANT POST OUTSIDE LINKS)

Application to Mod the driver so the system accepts it
(SORRY CANT POST OUTSIDE LINKS)

1. Disconnect from internet so windows dosen't automatically installs a driver itself;
2. Go to Add/remove programs and uninstall Catalyst Control Center;
3. Go to Device Manager and Uninstall your Graphics Card (put the mark where it says to remove all of the software);
4. Reboot your Laptop.
5. Install MobilityModder (Follow instructions on Mobbility Modder Website if you dont know how to use it)
6. Run the driver file and let it extract to C:Atisupport9-3_vista32_win7_32_dd, after it extracts close the New Installation window.
7. Open MobilityModder and browse to the folder where it extracted the driver i supposed its C:Atisupport9-3_vista32_win7_32_dd .
8. Click Modify;
9. After its done, close MobilityModder and go to C:Atisupport9-3_vista32_win7_32_dd and click setup;
10. Let it install and if it says that the driver is not verified click on install it anyway.
11. Reboot again and be amazed, at least i was!

The resolution will be at 4:3 ratio, to fix it set the game resolution to 1280x800.
28. Getting lag in MW2 maps: Highrise, Favela, Estate, Sub Base, Rundown.

It doesn't seem like a graphics issue but it is.

1. Go into your Modern Warfare 2 "players" directory.
2. Find the config_mp.cfg file, open it up in wordpad and run a search for r_drawwater 1.
3. Set the 1 to a 0.
4. Save the file and make it "read only".
5. Your "lag" is now gone.

You won't get VAC banned for it and the variable is not cheat protected so there's no problem playing multiplayer. It seems to be a problem with ATI cards. Setting drawwater to 0 does not actually disable water, there's still water in the maps so really nothing is lost but you have great performance to gain.
29. MW2 crashes and you get iw4sp.exe has stopped working Error.

The 'Aerium88' fix

If you have a dual or quad core system and you can play 10-15 mins then you can to try this :

1. First : Open taskmanager and go into processes tab.
2. While taskmanager is open, THEN start singleplayer.
3. When singleplayer starts it will come up "iw4sp.exe" in the list.
4. Quickly righ***ick it and go to "Set Affinity" and uncheck one of them and press OK.

Obviously this only work for people with Dual-Core Processors.
30. Remove Background Music in Modern Warfare 2

In C:|Program files|steam|steamapps|common|call of duty modern warfare 2|miles

There is a file called mssmp3.asi RENAME it to mssmp3.bak

This will remove MW2 game music sounds (ie, lobby music/music in beginning & end of round)
31. MW2 iw4mp.exe crashing problem.

Turn off the Antialiasing. And change MW2 graphic settings to high or normal.
32. Installation Error (53) COD: MW2- Multiplayer.

Installing 1.0.174 patch from 1.0.172 gives an Installation Error (53) CODMW2: Multiplayer.

Shut your Anti Virus Program down untill MW2 is patched / installed correctly.
33. MW2 updated to 1.0.174 patch, now patch_mp.ff is wrong Version.

Download and replace with (SORRY CANT POST OUTSIDE LINKS)

(Back-up your org. patch_mp.ff in case above new one doesn't work either.)
34. Modern Warfare 2 menu and in-game freezes and lag-spikes

The 'Cooperdale' fix :

(Win 7)

When you first start the game the firewall will ask if you want to allow it to access your network.

If you answer yes, this should create two rules in the advanced section of the firewall control panel.

One rule is for udp, the other for tcp.

1. If you block both but have upnp enabled on the router, you'll have nat strict.
2. If you enable udp, you'll have nat open.

There is no need to enable tcp, and if you do you'll get the freezes and lag spikes.

So tcp incoming needs to be blocked with your firewall, whichever it may be.

With this firewall/router configuration you get no port scanning, ergo no freezes, with an acceptable degree of security.

Full forum post with more examples and solutions can be found here

For XP and Vista - Download PC Tool Firewall Plus
And block all the TCP ports for Sp And Mp

So what you need to do is :

1. Block INBOUND AND OUTBOUND TCP PORTS
2. Don't Block UCP Ports.


35. Cant find or hardly any Modern Warfare 2 MP games in playlist .

1. Sometimes it works just to let the game finding games. Then suddenly, can be more then 10+ min later, it says : Playlist has an update, the playlist update will be downloaded.... After that you can find games.

or

2. Clear the Modern Warfare 2 exceptions and re-apply MW2 MP/SP in the Windows Firewall.

36. Random MW2 in-game freeze / black screen

It is the display driver that is restarting after it crashed for some reason.

And it only happens at MW2, while other games run perfectly. So the source of problem is buried in the game itself or steam.

No solution for now ! Many waiting for a new display driver or MW2 patch to fix this problem...
37. [iw4mp2.exe] Black Screen & Hang - Solution

The symptoms (in order of appearance) :

- Splash screen appears
- Black Screen
- Mouse not hidden & working (green circle in 7 / Vista)
- To stop it : CTRL + ALT + DEL and kill the task
- Single player works very well

The cure :

1 - First make a backup of your COD:MW2 by using the Steam Backup.

2 - Select both of the COD games.

3 - Exit Steam.

4 - Go to your Steam directory and delete the COD:MW2 directory.

5 - Go to your Steam Backup directory that you defined in Step 1 & 2 and launch steambackup.exe.

6 - Relaunch Steam and start COD:MW2 Multiplayer, it should say Completing installation... and start just after.

7 - Reconfigure your whole Graphics settings and Key mapping. It's the only real flaw in the process.
38. New fix for some of the crashing & freezing in Modern Warfare 2

Random driver losses (black screen), wierd rectangles on the screen, hard crashes requiring a power cycle, and CtD's (crash to desktop).

Problem can be your video card clock speed. Often you buy a video card that is a little overclocked.

And MW2 is EXTREMELY sensitive to overclocking or better said... it wants a certain clock setting.

So get the clocking agent that's belongs to you video card ( nvidia ntune, ATITool) and downclock a bit till MW2 works correct.
39. Black Screen when loading MW2 Multiplayer

And you have to ctrl alt dlt to close the .exe of the MW2 game.

Solution : Search for a file called mp_playlist.ff or something and delete it.

XXX: Program Files|Steam|steamapps|common|call of duty modern warfare 2|zone|english <- to find mp_playlist.ff
40. MW2 Error message- main/iw_craig87_rb.iwd is different from the server.
iw_craig87_rb.iwd or can be a similar weird titled .iwd file.

These Error messages will be shown when IWNet picked a Texture Hacker as MW2 game-host.

Nothing that you can do about this. Just try to find a game that isn´t hosted by a Hacker...
41. A fix for game freeze at splash screen (Happens after the .177 Patch)

Open Control Panel go to Network Connections. Open it up and disable your ethernet connection.

Load MW2 multiplayer (or single player if it won't open).

Once you get the menu, switch back to Network connections without closing MW2. Enable your ethernet connection and return to MW2. Wait a minute or two then join a game!

Also, be sure to click "Play game" when prompted at boot. You may have to use "Shift + Tab" to bring up Steam from the main game menu. If you have your ethernet enabled it should start.

Hopefully this works for some or all of you. Until the Error is fixed this should let you play.
42. Modern Warfare 2 crashes, when I am host, on the second map.

Seems the "second map host crash" comes from STEAM.

You have to download the Steam BETA Client.

You can do this in the Steam Account Settings.


Steam settings >> Account >> Beta Participation >> Change it to: ON

and restart Steam.


This fixes the crashing if you are the host. The current MW2 Disconnects and Time outs are both result of same Error. Because most hosting players don't know about the above fix (yet).
43. MW2 rank 70 hack - For your safety Modern Warfare 2 has ended the game for security reasons.

YOU got hacked and now YOU can't play MW2 Multiplayer anymore.

Locate these files and delete them.
|Steam|SteamApps|common|call of duty modern warfare 2|players –all .stat files
|Steam|userdata|(some numbered folder)|(some numbered folder)|remote| – all stat files
|Steam|userdata|(some numbered folder)|(some numbered folder) – remotecache.vdf
44. Voice Chat Modern Warfare 2 Not Working

When you're on win7 you have to set the default sound devices depending on what you want, it doesnt auto switch anymore. Check your sound properties and make sure the right mic is selected as your default recording device.
45. Crashing randomly in SP and MP Modern Warfare 2

In the advanced graphic option menu of the MW2 game, if you set "Sync Every Frame" on, all crashing issues can go away both in SP and MP. Basically, this option means "Only render when my monitor renders", so if it is set to 60hz in Windows graphic settings, your fps will be locked at 60fps, which is good when you have fast enough hardware to support it. It prevents image tearing, and reduces heat since your video card will not work for nothing.
Note : you may have to play a bit with your mouse setting, as this setting affects input, but overall the game feels smoother.
46. Freezing on Modern Warfare 2 splash screen

If you've been having trouble launching Modern Warfare 2 since the 1/18 update, here's the solution:

1) Open your services panel by :

* Press the windows key + R (or open the run menu)
* Type "services.msc" and hit ok

2) Right click "DNS Client", and choose properties

3) Change "Startup Type" to Automatic

4) Hit Start

5) Hit ok, close services.

(?? Restart Steam ??) - Not sure if it's necessary

You can now play Modern Warfare 2! And if your overlay wasn't working, this fixes that too! This should also fix any other issues with other games not launching.
47. Modern Warfare 2 - IWnet_ Invalid Version Error

Solution: Verify integrity of game cache. To do this open the steam menu, right click modern warfare 2 and click properties. Go to local and select verify integrity of game cache.

or

Uninstall and reinstall MW2

Part 2

Problem #1: Call of Duty: Modern Warfare 2 disc is not recognized in the drive

Solution #1: (By Activision Support)

All background applications should be shut down prior to running the game.

1) Go to the Start bar and select Run. (If you are on Vista or Windows 7, hit the Windows key and the R key at the same time)
2) In the Run window, type in msconfig and hit enter.
3) Once the utility comes up, go to the Startup tab and hit the Disable All button.
4) Next go to the Services tab and check the “Hide All Microsoft Services” checkbox and then hit the Disable All button.
5) Hit the OK button and close the utility, and restart your computer when prompted to.

Please note that this method will shut down all background applications including your virus scanning software. If later on you decide you want to re-enable programs that were closed down, you can undo these changes by simply un-checking the Hide all Microsoft Services box and hitting Enable All on both the mentioned tabs.

The Windows OS allows you to have lots of different programs running at the same time. Sometimes these programs do not play happily together and create problems. Many modern games are very demanding on your computer. Some game problems can be solved by making sure that the game is the only program on the field. Limiting the number of other applications and programs running can help your system and program performance across the board, not with just games. Virus scanning and other security programs often use a large amount of memory and access the files on your harddrive frequently. This frequent harddrive access can slow your computer down if these programs are running in the background while the game is running. You should shut down as many programs as possible to lower the amount of memory being used before you launch the game. For Windows XP your system should only be using about 100 to 120 MB of memory before launching the game. For Windows Vista or Windows 7 that number should be around 700 to 1000 MB. You can check the amount of memory being used by clicking on the Performance tab in the Task Manager.

Once you complete the steps above then your system is ready to run the game. These steps can clear up a lot of problems you may be experiencing. Your performance may also increase because you have more memory free and more resources are available to the game. Not only can this make games run more smoothly, but applications can benefit from this, as well.
If you have multiple drives capable of reading the disc, then try installing from your other drive(s).

Check with your drive manufacturer for the latest firmware updates for your drive.

It is also extremely important to ensure you have the latest drivers and firmware for your motherboard components as well. Please contact your hardware manufacturer for instructions on how to acquire and apply the latest updates.

Problem #2: Can’t play Call of Duty: Modern Warfare 2 online / can’t connect to any multiplayer games

Solution #1: (By Activision Support)

Be sure that your computer is not behind a software or hardware firewall of any kind. This includes firewalls built into routers or other equipment, as well as programs like Zone Alarm, Black Ice, and the integrated firewall in Windows XP. Activision does not support the use of our games from behind a firewall. If it is not possible to disable the firewall you will need to open the ports for Call of Duty: Modern Warfare 2. Call of Duty: MW2 transmits and receives network traffic on ports UDP: 1500, 3005, 3101, 28960 and TCP: 27015 (SRCDS Rcon port). Additionally the Steam client transmits and receives network traffic on ports UDP: 27000-27015, 27015-27030 and TCP: 27014-27050 The exact details on opening a port is specific to your firewall. For more information check with the firewall documentation or manufacturer.

Another common cause of problems is a poorly configured router or connection sharing solution. If you are using a router, ICS, NAT or a software gateway you may have problems playing on the internet. This is because the router may not be forwarding the correct information back to your machine. It may be possible to get around this problem using port forwarding or DMZ. You can find more information on configuring shared connections for multiplayer gaming at PracticallyNetworked.com. Please be aware that like a firewall we cannot actively support using shared connections to play online.

The most common cause of problems though is usually the simplest - an overburdened network stack. By default many computers have protocols the average person doesn’t use; things like VPN or NDISWAN. You may want to contact your ISP to find out exactly which protocols you can safely remove. Often times network game problems are resolved by something as simple as removing unused adapters and protocols.

The problem may also be related to the status of your ISP or that of the server. Due to the dynamic nature of the internet and the variable levels of traffic, it is impossible to completely eliminate this error. If you are having persistent problems you may wish to try a different server, or just wait and play a little while later.

Problem #3: Call of Duty: Modern Warfare 2 encounters zone file error at launch or during gameplay

Solution #1: (By Activision Support)

Zone file errors are most likley due to a bad install or corrupt game files.

* You can verify the integrity of the game files in the Steam client. In the Steam client right-click on the game and select properties. Click on the local files tab and click the “Verify integrity of game cache” button. You will need to do this for the single player and multiplayer game executables.
* If that does not work you can try to delete the game content and re-download it from Steam. In the Steam client right-click on the game and select “Delete Local Content”. Once you have deleted the content you will need to re-download the content through the Steam client. You will need to do this for the single player and multiplayer game executables.
* If that does not help then you may have a bad disc. Try replacing the game at the store you bought it at. Remember that if you replace the disc you will need to completely uninstall and re-install the game.

If the game still does not work after uninstalling and replacing the disc then you may have a bad piece of hardware like a bad harddrive or stick of RAM. In this case you will have to contact your computer manufacturer to find out how to test and replace any hardware that may be failing.

The Windows OS allows you to have lots of different programs running at the same time. Sometimes these programs do not play happily together and create problems. Many modern games are very demanding on your computer. Some game problems can be solved by making sure that the game is the only program on the field. Limiting the number of other applications and programs running can help your system and program performance across the board, not with just games. Virus scanning and other security programs often use a large amount of memory and access the files on your harddrive frequently. This frequent harddrive access can slow your computer down if these programs are running in the background while the game is running. You should shut down as many programs as possible to lower the amount of memory being used before you launch the game. For Windows XP your system should only be using about 100 to 120 MB of memory before launching the game. For Windows Vista or Windows 7 that number should be around 700 to 1000 MB. You can check the amount of memory being used by clicking on the Performance tab in the Task Manager.

Once you complete the steps above then your system is ready to run the game. These steps can clear up a lot of problems you may be experiencing. Your performance may also increase because you have more memory free and more resources are available to the game.
