D600 EF won't open in Cmarea Raw 7.3.0.71

I have CS6 Extended ver 13.0.1 x64 and Camer Raw 7.3.0.71. When trying to open a D600 NEF file I get the message "Photoshop cannot open this file". Under Adobe supported cameras, it states that the Nikon D600 is fully supported as os Camera Raw 7.3. Any ideas
