Okay , My xbox won't read My new GoW2. It reads EVERY other game that i own. My previous copy of gow2 was scratched , so i bought a new copy. I can't even install it because it says it is dirty or scratched. I have black ops installed. I have enough room for it. But it will go to the main menu, To where it says "Pres Start" The flames in the back will pause, and it will say disc unreadable. I also opened up my xbox (I have enough experience to do this without hurting everything.) And cleaned the laser lens, Everything else reads except gow2. Help please.
