When I update my Nikon cameras, I use a cleanly formated card and download the new drivers onto the card and put it in the camera. The firmware updater checks for this and if everything is "clean" it installs the new firmware.
Check with the update instructions. If the file is compressed, you may have to "unzip" it before writing it to the memory card. It is possible that one specific memory slot has to be used. In the past, some of my updates had to be placed in a specific directory on the card.
