Hmmm... I haven't heard of that issue before. Does the error only show up when a memory card is in the camera, or does it not matter? Just taking a shot in the dark here, but try formatting the memory card and see if that resolves the issue.
Viewing them in the ps or formatting the card in the ps probably encoded them. Try doing a format of the card In windows and putting it in the camera and then viewing them in windows. It's a card error. I don't think anythings wrong with the cam.
