I put in the fresh game and played for a few hours. I went to the store for some refreshments. While I was gone, a friend of mine that was still there started looking at the options. He enabled the 3d mode and now all I get is a blue screen. Does anyone have any idea how to turn this off. I have tried deleting my gamertag and re-downloading it, formatting my HDD, the only thing I can do is play on a different gamertag. Any help would be greatly appreciated! I tried a few times to remember the path, but no good. Can someone possibly post the directions to get to the option?
