I've haven't been able to find many threads that are any help, but has anyone ever encountered the 'CF A Error' on the C300. Whenever I put a card into the camera I get this error message. According to the canon knowledge base it means the card cannot be accessed or is malfunctioning. I have tried three different cards and each time this error message occurs in either card slot. At first I thought the CF slot pins may have been damaged but the camera recognises that I have put a card in, it just won't read it. Any help would be appreciated.
