so, I fired up my 360 last night, with friends over for a game night, it usually turns into rockband night because we’ve all had a few drinks, and rocking sounds fun…  360 boots up and immediately tells me there’s an update that I need to do, so of course, I do it.  Rockband launches, oddly I get no “if you want to play on live you have to update the game” so I go looking, there’s no update file on the internal storage or the harddrive for the game, so, that must be safe…go back to the game and go in, everything looks good….all of my customs are showing up happy…try to play any of them, and boom, disc read error, clean the disc or reboot…of course we rebooted a few times, but, the problem persists.  All night the regular tracks and DLC worked fine, but, nothing on my flash drive worked…
Suggestions/Recommendations/Solutions?
Thanks in advance y’all!
