My best guess is that this is some form of file corruption - the firmware patch does affect management of thumbnail files. Did you format the card when you got the camera back? Or does this card have images spanning the period before and after the upgrade? If the latter, I pretty sure your file system is "confused" - you may be able to download with a card reader - you really should get one - costs less than a D60 camera strap
. When you have your reader, get the FREE utility "downloader" from
(by all means, buy the Breezebrowser as well, its excellent)
If anything can be got off the card, this will do it. Once the card is clear, make sure you format it before using again.
