My Nikon D90 produces an NEF RAW file. PS Elements 7 is giving me an error message saying the file is in the wrong format. I can go to a JPEG photo, do an "open as RAW", and it goes right into the RAW processing window. On the other hand, when I click on a RAW photo with "open" it gives me the error message. I have Scott Kelby's book on PS Elements 7, but I don't seem to find an answer to this problem. How do I open and process a RAW NEF file using PS Elements 7?
