I'm using OSX 10.8.5 for an operating system. I just updated PSE12 to 12.1. I am now able to open the .RAF Fuji raw files with PSE12, which is what I wanted to do. My camera raw system says I'm using 18.104.22.168. As long as I'm able to open the files with Elements, that's good enough.
Thank you so much for your answer and your help in getting to the bottom of my problem! It's very much appreciated!!
