Started Rock Band 1 up, felt the nostalgia of having 'Day Late, Dollar Short' on the menu screen, re-did the export which involves overwriting every song (Grrr).
Started Rock Band 3 up, tried Hysteria, disc read error. Restarted RB3, tried Beetlebum for good measure, again, disc read error.
Finally, I tried starting up Rock Band 3 without my gamertag signed in and picking Hysteria. Got a disc read error. ):
Hope this helps!
