Just 2 days ago my copy of Left 4 Dead will not get past the main loading screen. I have tried to delete the cache, formated the drive, removed the drive, tring to boot the game. None of this will get me past the loading screen. I am having this problem only on left 4 dead and not any of the other games I own. I hope somebody has a solution to this I don't want to call microsoft to replace the console since now I am on the 3rd one. Does anybody have something for me to try.
