I have just got Unreal Championship 2, 3 days ago, and found out last night that it has decided not to work in my Xbox (it did on the day I received the game) but it works fine on my brothers Xbox which is about 1 month older when the Xbox was officially released, my Xbox new Xbox Crystal (since October) and has the Samsung DVD drive, and i'm just wandering what the problem could be, there arn't any scratches on the CD, i've cleaned the lense with a lens cleaner, but yet the game still doesnt want to work. Every other game that I have for my Xbox all work perfectly and I have no problems with them, the game gets stuck on the screen where it goes straight after the black screen with the green X thing, the screen is the games copyright screen, and just freezes on this screen, I even tried leaving my Xbox on for 10 minutes with the game in but it didn't go past this screen. Any ideas other than to replace my Xbox cos I have a whole load of stuff on my Xbox I don't want to get rid of.
