R4DS SAV. problems.

So, I've got myself a R4DS, the original one, but now, all the save files aren't working anymore. I get things like: "The save file isn't working. Please try again" or something like that. Anyone knows how to solve this? And please, don't say things like: "Get yourself a Acekard, pal," because I don't want another flashcard/

Your save files may be corrupted.. It really says "The save file isn't working"??!??!?!?
