Backup Save State

[dechidus]

New to the ppsspp, awesome emulator. i searched the forums but cant find my specific problem. I love to use the save state function on the UI, but by mistake i overwritten a save state file with alot of hours of FF tactics. I see the backup saved state that i need (icon and a .undo file) but i click on it and it just show the jpeg icon, and the "load save state" file drop down menu is all greyed out. I tried everything and i cant figure out how to load that backup ppsspp created. So much thanks for any help!
