For a while, my family and I have been playing Rock Band 2 an 3. We have download RB 1, 2, and 3 songs that my brother download from his Xbox account before he signed it up for XboxLIVE.
We've realized that we can't play the songs without him being signed in. Now that he is on XboxLIVE the songs stopped working. How do I get the to work again?
