Make sure of two things:
Your Xbox is fully updated.
Your chosen memory device is the one that contains your maps.

This happened to me for a while. There has also been some issues with Theater playback of some material. I don't know the cause for the map loading failure or the theater film failure. Bungie seems to have some media issues on their servers.
If it says loading 0% for a while, just let it sit there until it begins to load.
All I did was restart my Xbox. If that doesn't work, turn it off, leave it unplugged for a few minutes, then plug it back up.
Make sure of the two things I mentioned above first. Add details to let me know what happens. Good luck.
