1. Make a Backup of Profile folder
2. Download the Mw2 from Alteriwnet
3. Delete the entire MW2 folder
4. Unzip Mw2 (the one you got from Alteriwnet)
5. Copy the BackUp Profile folder into the new Mw2 folder and replace if have too
6. Run alterIWnet_configure.exe as admin setup your name
7. Then run iw4mp.exe and it should run
Note: Sometimes if it still get "Steam Authorization Failed" then repeat the steps but DO NOT START iw4mp.exe. Wait till the next day and then try RUNNING it. I hope this helps.
Im not sure if were allowed to post link to this video on YouTube but here you go:
Hope it Works!

Idk if I can post in here, but I have this same problem, yet I'm not using hacks. I backed up my profile and ever since then I get the error. I tried deleting the logs, re-installing the game, even starting a new profile. Nothing works. Any help?
Nevermind, I looked at a thread on alteriw.net and deleted the 5 log files and it worked.
