I continuously receive the same error "File format

When you recieve a "Card Error" or "Card Not Initialized" message, this indicates that your memory may be temporarily corrupted. This can be due to not formatting your memory card on a consistent basis. Most consumers will use the "delete all" feature and continue to take pictures. By doing this, the file format of the card may become unstable.<br /><br />We recommend formatting your memory card in your camera after saving the images from your previous shooting session. Once a memory card is formatted, the images will not be recoverable.<br /> <br /> If this doesn't fix the Card Error, try replacing your batteries with a new, fresh pair of batteries. Also, if you haven't tried already, replace the memory card with a known working card and see if this fixes your error.
