Okay, so I was playing Brawl earlier. I was doing random wi-fi battles. While I was in the waiting room, the music suddenly stopped, started again a few seconds later, then stopped again. A screen came up saying "An error has occured. Please remove the game disc and turn the power off." So, I did. When I turned it back on, I put SSBB back in. Nothing happened. It did not even start spinning, it was like it did not realize there was a disc in. The wii showed "Unable to read disc". I took SSBB out, and tried some other games. They all worked fine. But SSBB doesn't. There aren't any scratches or marks on the disc. Any suggestions?
