[tommy0709]

Does any one know what this screen means and if so we would really appreciate the info on it?

Looks like the account that bought the DLC is deactivated. The account has to be activated for the DLC to work.

This is assuming that you are on PS3, if it Xbox 360 or Wii, then I'm not sure since I'm on PS3 only.

yes it is ps3 and i have no idea what that is that u r talkin about "DLC" it lets us play songs as a band tour just periodicly pops up the screen saing the message i yped on my initial question

I was talking about purchased song tracks from the store(DLC+ DownLoadable Content) Re-downloading the tracks from the account that bought them should help.
