I'm having some issues loading maps on Halo 4. This has been occuring since the game update was released last Sunday. I can't load ANY maps. This includes DLC, maps that came with the game, Spartan Ops and the campaign. I've tried playing offline and it still doesn't work. I keep getting a message saying "Player failed to load content. A player may be missing downloadable content".
This is the second time I have had this issue. The first time was approximately two months ago, again just after a game update was released. I had exactly the same issue which lasted a week until the next game update was released.
