My friend and I are both experiencing a problem where the game’s “Checking Downloadable Content” screen is not disappearing, and just seems to be constantly loading.
This problem is likely only happening for anyone currently trying to load up their game. We have tried restarting our Xboxs, clearing system cache, and re-dowloading the DLCs.
Me too
Xbox Live is having the problem. It’s not just Halo 4 but all games that check downloadable content.
yeah it just keeps loading. i restarted my router, no difference. i even went direct with the ethernet cord & plugged it into the Xbox. no Change! im, about, to Rage.

Calm down there buddy. Go outside, read a book, or watch some TV and check HERE for updates.
Too late, i already raged.

OK, I lol’d. Humor is the best remedy IMO.

Yeah, difficulties in the last couple of days. Servers are too much laggy and everything.
Halo 4 was barely playable.
Hope they’ll fix this soon.
