Hacking Acekard file corrupted

[Xeonneon]

SO i was playing pokemon rangers gaurdian signs. It froze(i was okay with that) but when i loaded the game, it says the previous save file was corrupeted, sorry you will have to start a new game.

How do i get this fixed!!!

Could you check the save file's size for me?
(Acekard -> hold the 'cursor' on the save file -> Press 'Y')

You might have the same problem as I've had several times.

Could be a few things.
Might've frozen because of anti-piracy (update your AKAIO firmware to 1.8.1)
Might've been a microSD issue, try formatting it with Panasonic SD Formatter.
Might also be a good idea to make regular backups of your game saves.
