You have to format the card in the camera before you start using it.
Download the images you have (formatting will wipe the card).
Edit *************************
If you formatted it in the camera, then that should be fine. It has to be done every so often to refresh the File Allocation Table.
The manual does say that if you get a "File Error" then delete the file...which sounds pretty inadequate to me. No explanation is given as to WHY you would get a "File Error".
BTW Your camera is just a camera. It is used to get pictures that you take home and download onto your computer. Store them there or upload to sites like flickr, facebook, and the rest for sharing. Cameras aren't designed for long term storage.
