Adobe Creative Cloud Error stops me from using Dropbox for backup

Two days and about 5 hrs and no luck. I need to use my 1T Dropbox for backup for desktop and documents on my Mac. Should be simple, right? Well, as difficultly simple as everything is today. 

I continue to get an error that states "Adobe Creative Cloud error" (See attached). Of course, when I click on "how to fix this error" I'm supposed to some how magically figure out what in 660gb is causing the error. 

I have nothing in the adobe cloud; no documents; in theory, noting from PDFs (I say in theory because I can never figure out where anything is actually saved); my cloud says there are no documents. I do have some images in the stock photos in a library (where the professor is standing with the candelstick), and I downloaded them. I also have repeated attempted to delete on that we no long want but I have given up. That comes back like a single sock from the drawer. 

So, I attempted to uninstall adobe creative cloud and I got a message that I couldn't because I have apps that are installed that use it. How convenient is this! 

I need those apps and I need to also backup into a cloud I already pay for. So, do I uninstall Stock, PDF, DC, Reader, etc. or is there a trick, the secret that I don't know to ask that I don't know?
