Cant think of a better title for the thread but here goes. I have lent a mate of mine several games recently and he has problems playing some of them. He could play the 1st 4 characters on 99 Nights then it wouldn't let him play the next ones. Some tracks on Burnout Revenge are permanently locked for him, even the early ones. There are other games/problems but I can't remeber them all. He is on-line fairly often to get the updates for the games. Has anybody else had this problem or can they give some advice. All the games can be played completely on my machine.
