I have been using the camera for 6 months with no problems. All of a sudden it started showing me the message "Card not Formatted". I clicked on the options to format. I got the message "Data is being Formatted" for a couple of seconds", but then got the message "Card not Formatted" again. With this message, I cannot use my camera. I tried my memory card into another camera and it worked. I tried a workable memory card into my camera and it gave me the same message. So I concluded that the problem is my camera. What should I do? thanks, Isabelle
