Problems loading campaign missions

[Radar rager]

For some reason I can't load the mission "reclaimer." Everytime I attempt to the game loads to about 24-32 percent (though once it made it to 56 percent) before resetting to 0 percent and eventually reading a message that "players failed to load content. A player may be missing downloadable content" which is ludicrous because I constantly see the message "checking for dlc" in between pages. I have access to the Internet. Only other thin that's odd is the mission requiem doesn't have a highest difficulty completed listed on it. Honestly this is really annoying to have a brand new game break like this I literally can not advance through the campaign past reclaimer because of this. I've never had problems like this with any other halo game.

I'm having the same problem......so far no news about getting it fixed or that I need a new disc. If you call xbox they only say that they are aware of the problem and are working on it.
