Why will Elements 15 not open RAW files from my camera?

I have a Nikon 7500 camera. In June I was able to open and edit RAW files from this camera but now when I try I get a message saying that Elements 15 cannot open files from my camera. It will now not even open the files it previously opened in June. I have all the latest updates for Elements 15 and when I check it says that it should open files from my camera.

Is there some fix or update I need to download so that it works with my camera again?

PS: Elements will still open files taken using my Nikon D7000 camera.
