i backed up socom using prassi. it worked fine but when i shut it down and tried to load my saved game it goes back to please insert ps2 game screen. all my backups work with no problem. i use verbatim dvd-r disk, i have 80 dvd-r games. but this is the first one that doesn't load with the memory card. help?

i was using gameshark v1.9 when i tried to load the game. but then i tried gameshark v 2.0 and it worked.
