Halo 4 Campaign issues?

So I tried to play the campaign yesterday and today, but had issues with it. I tried to play it yesterday and go through the first mission, but it put me back to the menu once it was done. I tried to play the second mission, but it said i’m missing the required dlc. Today, i tried again and the same thing happened except instead of missing dlc, it loaded the game to 100% and then restarted the loading process over and over again. Anyone know whats going on?

Thanks

This is a really crazy issue. The first part sounds fine, but the missing dlc thing sounds like a different problem. Try reseting the cache on the xbox. If you don’t know how to do this, google it, it’s pretty easy.
