Anyone have a similar problem, or a solution?

Yes, just re-download it try. If not, call Microsoft.

Then I dont know that sounds really odd, you might wanna call microsft support even though those people are the worst to deal with

A friend of mine had the same problem as this, we figured out that the problem was that he was downloading it from the xbox live marketplace.
We fixed the problem by downloading it from the black ops store, you will not have to buy it again so don't worry.
Incase you don't know how to get to the store, from the main menu, choose multiplayer, and after you have connected, the 'store' is above 'main menu'

Hope this helps.
