Sup Guys
Here's a few things i learnt to help your "Combat Arms Has Stopped Working" Problem:

Solution 1
1. Make a new folder in the nexon folder, then put combat arms in that folder, so the directory will look like this:
(C > Nexon > Nexon > Combat Arms
2. When finished previous step do this, Open combat arms client (CombatArms.exe) straight from the folder
because if you make a short cut it will not work.
3. Click "Game Start" when you finished and wait for it to load up

Solution 2
Part A
1. Right click your Combat Arms short cut icon and select Properties
2. Go to the Compatibilities tab and check “Run this program in compatibility mode for:” and select Windows XP SP2 in the drop-down menu
3. Restart your computer
4. Click "Game Start" and see if it works, if not continue to part B
Part B
1. Right click your Combat Arms short cut icon and select Properties
2. Go to the Compatibilities tab and uncheck “Run this program in compatibility mode for:”
3. Restart your computer
4. Click "Game Start" and see if it works, if not try other solutions listed

Solution 3 (anti-virus users only)
1.Make sure Combat Arms is on your anti-virus allow list or temporarily disable your anti-virus so Combat Arms can run. Anti-virus programs tend to block other programs if they are unfamiliar with it.

*AVG Users Only*
AVG has officially added Combat Arms to their Whitelist, but this adjustment will not take effect until you update your AVG software. If you currently use AVG, please update your AVG software so it will allow Combat Arms.
If you need to restore deleted files from AVG Virus Vault you can do
it this way:
1. Open AVG's user interface
2. Choose "Virus Vault" option from the "History" menu
3. Locate the file that was incorrectly removed and select it (one click)
4. Click the "Restore" button

Solution 4 (Windows Firewall users only)
Windows Firewall tends to ask for your permission to proceed but if it doesn’t it may be preventing you from accessing Combat Arms.

1. Go to your Control Panel and double-click on Security Center
2. Find the Window Firewall and there should be an option to “allow program through firewall”
3. Browse for Combat Arms and add it to the allow list
4. Restart your computer.
5. Check if it works, if not try the last solution

Solution 5
This is the last option as your files may have been corrupted.
1. Make sure you uninstall Combat Arms thoroughly and correctly before reinstalling
2. Restart then reinstall
3. Try opening combat arms if it doesn't work restart after reinstallation
4. Try again,

if none of the above worked then your practically screwed nah i'm joking, just wait for the next nexon patch Have fun waiting

PS : i dont think nexon will compensate you log in, but im only guessing
Have fun
