iso's stopped working

[lolhacks]

so all the sudden my games stopped. what i think was the cause was when i turned my psp off while a game was loading (stupid), then i took the memory card out while it was off but put it back in, i turned it back in and the psp froze so i took the battery out then turned it back on. after i did this i tried to play some cso's and none of them worked.what happens when i start a cso is it goes throught the starting logo then goes back to the main screen and gives me the cant read error. i tried putting a blank .txt file in psp/game and psp/iso to like reset it but nothing happened. i also tried reinstalling my cfw but does nothing. i also tried deleting the cso and putting it back on the psp/iso folder, still doesnt work. i have 5.50 gen-b in case that helps. plz reply
