...Please help.? I have a SanDisk 256MB memory card I use in my digital camera. I put it into the SD upload slot on my printer/scanner in order to save the pictures to my computer. I was doing so today and suddenly it said the pictures could not be copied and the green light on the printer turned red. Now my camera will no longer read my card saying "This Card Cannot Be Used".

I didn't do anything differently than I normally do. What is wrong with my card and how do I fix it???
