I don't get a photo preview in bridge of my raw files, just the NEF file thing. Then when I click to open them I get a message that says: "If you are attempting to open a raw file from a digital camera, make sure you have the latest Camera Raw update installed via Help > Updates" "If the problem persists, visit the following link for more information: http://www.adobe.com/go/kb407111". I can't seem to figure out what to do! Help Please!?
Sorry I can't help you but I have the same problem!! I have asked Canon - Apple and Adobe and I keep getting pushed around!! It is so frustrating!!!!!!! Good Luck!!
Usually the problem with a newer Nikon camera is that the NEF files have been transferred or viewed with obsolete Nikon software, like Nikon Transfer for View NX, and those change something in the header of the raw file that makes it unrecognizable to Adobe products.
For new images, the solution is to either stop using Nikon products to transfer and view your files or update your Nikon products to be as new as your camera.
