I bought Halo 4 brand new from gamestop at the end of November. I have tried installing and reinstalling the multiplayer features and even tried a new disk and neither of those things helped. I have been playing other games on my xbox with this hard drive and the only other game I have had any issues with is Mass Effect 3 Omega DLC and this one map. I can play every other map in the game with no problems. How can I fix this?
