Did that too, nothing. same problem. no change.

Just tried launching the game itself from the instalation folder again, gave me this application error

BlackOpsMP.EXE - Application error

The application was unable to start correctly (0xc0000022). Click ok to close the application.

did anyone resolve this? I been having the same problem for a couple weeks now. I've tried all the fixes with no luck. Received the following from Steam Support....


Thank you for contacting Steam Support.

If you are running in Windows Vista, Windows 7, or Windows 8, please completely exit Steam, and right-click on the shortcut which you use to launch Steam and select "Run as Administrator."

If you are running in Windows XP, take the following steps:
1) Exit Steam.
2) Go to the "Start" menu, select "Run", type "regedit" and click "OK".
3) Navigate to the following registry key: \HKEY_CURRENT_USER\SOFTWARE\VALVE\
4) Right click and select "Permissions"
5) Check the "Allow" boxes for "Admin" and "System" for both "Full control" and "Read".


If you have not already installed the Multiplayer component for the game, please log in to your Steam account, then type the following into a web browser and press enter:
steam://install/42710


Then, verify GCF for both "Call of Duty: Black Ops" and "Call of Duty: Black Ops - Multiplayer" at least once:

NOTE: There may be files that fail to validate. This is normal and can be ignored.


If the problem remains, you may need to manually run secondary installers required by this game.

Exit Steam entirely.

Browse to your Call of Duty: Black Ops installation folder (Usually C:\Program Files\Steam\steamapps\common\call of duty black ops\)

You will need to run the following installers:

...\steamapps\common\call of duty black ops\redist\vcredist_x86.exe

...\steamapps\common\call of duty black ops\redist\DirectX\DXSETUP.exe


Then, restart your computer and test the issue again.
