More likely to be a card problem Andy have you tried another card?
Firmware has to downloade off of Nikon site www.nikon.co.uk

Check you've not bent any pins in the card slot... If you have, then the pointy end of a metal propelling pencil can sometimes be used to very gently straighten them out again.
Fixation are very quick but I suspect it won't be cheap give them a call tehy can usually give you a quote over the phone or if your a Nikon NPS member they are very quick.
