Your Signature says you have both a D80 and a D300.
The D300 is creating the .NEF for RAW images.
Does the D80 also do RAW format ( apologize for not knowing - but I am a lifetime Canon person ).
If the D80 does RAW have you put them into iTunes.
In other words if it works for D80 RAW images and not for hte D300, Nikon changed something! 😱
I know this may sound stupid, but I once owned a Canon 10D, shot RAW with it from day one and all my programs liked it. I since acquire a 30D and somewhere along the line Canon change its RAW processing.
Canon 10D produced *.CRW files.
Canon 30D produced *.CR2 files.
At least they changed the extension, which clued me in to my problem.
