Hi, I downloaded Windows 7 yesterday and I got it work... But when i wanna play cod4 it doesn't work. When i launch the game it says ""DirectX encountered an unrecoverable error. Check readme for possible solutions". I know that you need DirectX 9.0c but i got DirectX 11 and I don't know how to change it. I downloaded DirectX 9.0c and i installed it and restarted comp but still didn't change. I try to find DirectX 11 in my computer to unintall it or something but i can't find it. So please help me! Thanks, Qwerty.
