Hi I bought my first SLR ( a D90 ) And also bought the FastPictureViewerCodac and installed the plug in but can't get paint.net to load my NEF files. I'm using paint.net 3.5.5 and the latest version of the codec. The codec is working fine. I'm seeing my NEF files in windows picture viewer and I'm seeing my thumbnails. Any advice on how to get the NEF files to load??
