I just reinstalled CS3 on my refurbed Mac G4. When I try to open an Nikon camera raw file (.NEF), I get the error message, "Could not complete your request because Photoshop does not recognize this type of file." Prior to a hard drive crash, I opened .NEF files using CS3 on my G4 frequently with no problems. I have reinstalled the software twice and tried importing the files from the camera using Bridge all with the same result. Any suggestions would be appreciated!
Which Nikon camera exactly?

If your camera files could be imported before then update to ACR 4.6 - the latest Camera Raw compatible with CS3
