problem screen shot

Open regedit (press Windows button + R and type "regedit.exe")

Then go to HKEY_CURRENT_USER\Software\fourDeltaOne\IW4M\

Edit the value of "GamePath" (right click -> Modify...) to wherever your game files are located (assuming you moved your game folder to a new place).

 

 

Copied from FAQ

Open regedit (alt+r "regedit.exe")

Didn't read it properly since I copied it from the common errors thread. But it seems like I can't rely on that
