Hi NITA, all I can think of is perhaps your camera's memory needs formatting. The memory may have become corrupt and needs a clean-out this way. (these things happen). It wipes the memory card completely. Does your camera have this facility?, it should be in the same place in the settings near the delete pictures option? Remember though, if you do format the memory you will lose all pictures for good. If you are uncertain or want to try to keep the pictures in the memory, you could go to a shop that sells digital cameras and ask them to try your memory card in another camera and see if it's the card or camera with the fault. Good luck..
