I came home today to play a little of my PSP game. i had finished one level and it told me it could not autosave and i would have to do so manually. thus i tried and it said there was no memory card. i then quit the game and looked at the PSP main menu which also said there was no memory card. i left it alone for 10-20 mins and still no memory card. so i check and sure enough there is a memory card in the PSP. i have taken it out several times and put it back in. anyone know how to fix this or do i just have to buy a new card?
