Error loading file (Iso/cso) File corrupt. Help.

[Bill_Rizer]

Well, I've been testing out this cool emulator about 2 days ago, and did not had any problems at all until today that I tried to put on some more roms on the emu when suddenly all my games were not detected until I moved them (To Psp/Game) folders.. I read on a different thread that some errors are led by using incorrect folders, which I think it's not true because I used to had my roms on a Backups android folder.. well after importing my files to GAME it did detect them, but with an "?" stating that the file is corrupt.. I would appreciate some help folks..

5 minutes later I tried to create an ISO folder and try again, but it was not sucessful.. I still have this error.. Now i'm afraid of losing my savestates. (Because normal savedatas won't work for me either.

Now I just figured out the games had 0 kb but they're still taking space in my microsd.. I didn't installed other apps that could contain virus or malware.. I'm really dissapointed.
