My wii is 3.3U and i decided to try the DLC for Rock Band 2 with a back up. I bought And Justice for all then i played it. In the Middle of the song i got a "error has occured". now every Wii Game i put in back up or not gets an error has occured. The Only thing that works are Gamecube games. If it Makes a Difference i got my wii launch day
