ERROR: File System is too Fragmented! for Final Fantasy Crystal Chronicles

I have a CycloDS Evolution and I have firmware version1.3. I've tried downloading from different Rom sites and have tried the (E) version as well. It seems to start then I get "Error: Filesystem is too fragmented". Any ideas on what's going on here?

I think you'll have to backup everything and reformat your MicroSD.

Makes sense, thanks

That worked, thanks for the idea.
