Master Collection / Creative Cloud Issue

[JN AIPSCC]

I purchased Master Collection (CS) Perpetual in 2015. I was told to also purchase a Creative Cloud subscription.

I later learned that I did not need a CC subscription and cancelled it.

Now, I can’t open Illustrator & access my files.

Adobe  tech support reloaded my Master Collection and told me it would solve the problem.  It did not.   

I was then told to uninstall CC completely and re-install the Master Collection.  A pop up screen told me I could not uninstall CC because CC Applications on my computer require it.  Also very worried I will lose my Illustrator files.

Help?
