So, recently I've been downloading a lot of custom songs (not really a lot, like 15). I plug my flashdrive into my xbox, title update 4 and everything, and I go to quickplay. The songs are there, the previews work fine, the album artwork is fine, difficulties are fine, but whenever I go to play them, after I select my difficulty, it crashes on the loading cutscene and says "the disc is unreadable", but the disc is actually in mint quality. I've tried loading a custom on RB2 and it works perfectly, so why is it only doing this on RB3?
EDIT: Never mind, TU5 was hiding in another place on my Xbox. All is well now.
