My brother moved the 360 console while he was playing the game. He didn't accidentally move it and now there is a "perfect circle scratch'. This disc was Black ops, and no longer can I play any maps (Zombies or Multiplayer) online or offline. I tried someone else's disc and it worked perfectly. My brother wants me to help pay for a new one because he says that because I sometimes left the game in the console, or left the game laying out outside of its cover, that this is also part of the problem. When he first started playing the game, it worked fine. And then in the middle of the match, he moved the console. The game still loads up to the point where you are about to start playing on a map, and stops there. I think this is proof enough that it's his fault and should pay for the new game in its entirety, but he still wants a confirmation. Please respond quickly.
