I have been using my D600 for a few months and shoot JPEG/RAW. The last three downloads I made I was unable to open the RAW file in CS6, previous folders still had no problem could still open those RAW files. I asked Nikon if they knew why and they told me they could not respond about 3rd party software. It was not CS6 it was Nikon Transfer. The last few times I downloaded files I opened Nikon transfer and according to this blog ( http://forums.adobe.com/message/4949193 ) that was the problem. Nikon transfer v1.x corrupts the RAW file from Nikon D600 camera. I still had images on my SDHC card and downloaded them with Nikon Capture NX and had no problem. Also in the blog was a link to a program that would repair the NEF files and it worked great. Here is link to that program if you need to use it. Has anyone else experienced this problem. Nikon was no help.
