Try cleaning the contacts on the memory card(usually sraping them lightly with a knife helps with contact) and if that doesn't work try formatting the card in your computer.

It seems that many people think that sending a camera back to the manufacturer is helpful. Most of us want help to fix it ourselves. If it is under warranty most know enough to send it back. If it is out of warranty the repair cost for most problems is more then it cost to replace it.
