Data song missing, can't play DLC Offline

[MrTofu]

Right now i lost my internet connection so i can't connect to XBL, but too late i realized that some songs like the Killers and red hot chilli peppers DLC throw an error message when i try to play them, something like "there is data missing from the song", but that doesn't happen when i'm online.
What's the fix for this?

Thank you.

Welcome to the Rockband Forums.

Are still signed in with your same Gamertag?

There may be another hoop to jump through as well. I am sure one of the XBOXers will chime in shortly.

Sounds like the licenses for your DLC belong to a different Xbox. Did you get yours replaced at some point, or buy DLC with your hard drive attached to a different Xbox?

Either way, you're going to have to transfer the licenses to your Xbox to be able to play them offline. You can do that here:
