Plutonium

Chiller99 So, there's a section that you can click on that's the options for the game, and one option is for the directory. Basically, go to where you have your main game files for the game (for me, although I only have BO1, the path is C:\Program Files (x86)\Steam\steamapps\common\Call of Duty Black Ops), select the folder that the game is contained in, and try again.
