Well... I was about to go into a game, it kicked me out to the title screen. I logged back in and it said I didn't have the multiplayer and I should download it from the Halo 4 Disc 2. So I popped that sucker in and it says "You already have this downloaded." and whatnot. So I put in Disc 1 and it says the same thing. I restarted my xbox, but no luck. I don't know what to do....
