Problem with new Memstick

I was running 3.90 M33 (version 2) very nicely on my 2 gig scandisk ultra 2 memory card.

I then bought an 8 gig sony memory card, and copied the files over (not the memstick.ind ones ofc) to the new memory card.

Since then, everytime i try to run a backup or anything i get told the game could not be started, on BOTH memory sticks!

How wierd is that?

Any suggestions?

You could try reformatting the memory sticks, don't forget to save the stuff on the cards before you format it. (Format the cards by the psp not the computer)

also where did you get it?
it could be a fake one
