I've recently run into a problem. I bought a bunch of DLC from the Rockband store (this is on my Xbox 360 by the way). Saved them to my HDD, had no problems playing them for the longest time.
Was over at a friend's house, and recovered my gamertag to his console to play some MW2. Deleted my GT before I left, went home, recovered my GT, and downloaded the new 360 update for USB storage (which is pretty nice).
Tried to play some DLC, but only 2 or 3 out of 20ish songs show up in my list no matter what I do or how many band members are playing. Checked my HDD, and they are still there. Re-downloaded them anyway, still didn't help.
I've also tried googling a solution and someone recommended deleting a "Rockband Download Data" file, which appeared to work for some people..but not me.
Anyone else ever run into this problem and have a solution? If not, who would I contact to get this sorted out?
Thanks for the help.
