Major problem. I took a bunch of pictures for NYE with my Pentax Optio S40. Today, when I was looking through the pictures, the screen said "Cannot display the image or sound." I took out the memory card, placed it into my pc and tried to extract the pictures, but they are not there. When I click properties on the memory card, it shows that the card is full (232MB of used space), but my pics are not there. Is there anything I can do? Or is there any other means by which to get that data off? Or will it be corrupted? I'm extremely depressed in losing the photos with all of my friends. Thanks in advance.
