O.k. so recently my Xbox 360 broke right (crappy day that was) so I was forced to re-download all my content on a new Xbox. The problem I am having now is that after re-downloading all the DLC I have for New Vegas (Classic Pack, Dead Money, Honest Hearts, Old World Blues- In that order.) The game when starting states that some of my DLC may be corrupt and needs to be re-downloaded again. When I check the installed DLC list it only showed Classic Pack and Dead Money as being registered. Has anyone had this issue and could it be that an update for it didn't install properly? Because I had just re-downloaded so it shouldn't even be corrupt.

On a further note, it only plays the DLC when I am playing while connected to Xbox live.
