One of the main questions I had was this. I was alarmed even further as .nef files are supported by Nikon Camera’s and if this program does not work what will?

I had a Nikon D3000 and I was using Capture NX2.0.0. and all the picture previews came as unrecognized files (If the file is recognized you will see a preview).

So if you get the message “Warning Cannot Load File” with the path and file name.

Please check with the version of Capture NX2. The person who had this issue was using a D300S and had the version 2.2.0 at that time the latest was 2.2.4. At the time of writing this the version is 2.2.6. After I installed the latest version all the pictures came up properly.
