    This happened to my 640, and I could not find anything that might make it not recognize the card. One thing I didn't try is cleaning the contacts.

    I'll see if I can try that, and report back. You may be able to put a little rubbing alcohol on a Kleenex, and gently clean them.

    I ended up retiring the 640 due to this issue.
