Anyone ever have this problem with COD?

I have made a backup of call of duty and used it with the no-cd crack. When I hit new game in the main menu it pauses the music a moment then starts it back up and never starts a game. Anyone have an idea if there is something wrong with my backup?

Yeah, i have the same problem. Look on Activision's web site. They explain that the files need to be certian sizes. Also, when you install it, does it hesitate or even freeze up at 89%?
