I was having fun playing COD4 on my PC and I got to the intro video for the Blackout mission and the loading bar went a little bit and then the game crashed. I reinstalled and the same thing happened. I'm not 100% sure but I think the problem is the disk because I borrowed it from a friend and it has more scratches on the back of it then there are letters in a 500 page book. And yes I did try cleaning the disk. I feel like maybe I should torrent the game?
