file corruption??

Hi, I downloaded Rhythm Heaven for NDS but I keep getting this message saying "The save data could not be accessed. Please turn the power off and reinsert the DS card." I have tried this plus also re-downloading the file again onto my DS card but it doesn't help. Is the file itself corrupted?Thx!
