Yesterday was the first time m3 game manager has ever crashed on me giving me a runtime error. It happens when trying to delete a rom off my sd card, the saver manager comes up then program crashes. The problem I am having is that it has somehow locked the sd card (actually all sd cards) - computer says all cards are write protected. Computer sees the card connected and I can read and copy files but cannot delete. Game manager will also not write to card as says card is full. I have tried uninstalling and reinstalling game manager - problem still exists. Anyone have any ideas? ...a few hours later After finding a different portable card reader - game manager and sd cards now work fine. It was the card reader suddenly giving up (making game manager crash).
