EV Flash Help

I'm using an EV Flash 3in1 with the Acekard2i using AKAIO1.5.1. My GBA games were working fine, but yesterday all my GBA saves were deleted! Is there any way to get them back? If not, how can I prevent this from happening again.

If they have been deleted, then NO you can't get them back...sorry.I'm unsure of how to prevent this from happening again...i can just answer the first part. :P
