Sansa Clip+ MP3-Player >> "Not enough space for music DB. Please free 90MB."

I was finally able to reformat my player by plugging it into a different computer.  For some unknown reason my computer would not recognize the player and trying to reformat it crashed the “disk management” program.  For others with the same problem, follow this link and make sure to attach your player in MSC mode (also explained in the link).
