Well, I got home from school and I wanted to get on the Xbox. My Xbox 360 auto starts my CoD; Black Ops disk. I connected to live, and I joined a Capture the Flag match, only to get a blank gray screen, and an error message saying:
Error, Downloadable content has changed.
I didn't have this error before I went to school, and I have never had it in general. Any ideas whats up?
