Photoshop CC 2015.5 Doesn't Recognize CR2 files? [OSX]

I updated photoshop CC 2015.5 (v 17.0.2) through my creative cloud and now I can't open CR2 files. When I click Photoshop CC-- About Plugin-- Camera Raw, a pop up comes up and says "Could not complete the Camera Raw command because the file was not found." Why am I suddenly unable to open this file type/why is the plugin suddenly gone? Is there a way to revert back to before the update so that I can open this file type again?? When I look in my installed apps on my creative cloud page, it says that I have Camera Raw CC (v 9.6.1) downloaded.

I tried downloading camera raw 10.5 and 11.3 from here (Camera Raw plug-in installer ) but it won't let me because it requires OSX version 10.11 or later. I am honestly not good with computers/don't understand any of this, I just need to edit these photos for my business. Someone please help!!
