Hello, When I play Black Ops II what happens is that every once and a while I'll play and the scorestreak will turn into a big x when it appears on top of the screen. Also the sniper scope disappears. Its weird because when that happens, after the game ends the game says its unreadable and brings me to the dashboard. Also when I launch Grind or Mirage the xbox freezes I deleted the map pack and deleted it many times. NOTE: Deleted game and all files MULTIPLE TIMES but no luck. I even bought a new game, same thing.
