Yeah, and I knew it was coming because the same thing had happened to my brother's of the same brand. The only thing that was lost was my DDRE2 data, which wouldn't copy to another memory card beforehand and I couldn't use cheats to unlock all the songs. I lent the game and my dance mat to my brother's friend since I decided to take a loooong loooong break from it and I never saw it again. I am a sad Jessweeee♪.
