Lightroom Classic CC 7.3 problem [vs stand-alone]

Hello,

I have purchased Lightroom 6 from retailer. Just the single program with one time payment. I had used it since July 2017 without a problem. Some point it updated and worked well also. NOw came this 7.3 version update. My Creative Cloud App updated it automatically to that version, without asking do I want to update. Previously I had version 7.2. After updating to the version 7.3 I had lost all of my color adjustments in Lightroom Develop mode. I can't adjust Saturation, Vibrance nor HSL. I think that it mixes it somehow with the new update which is apparently not supposed to work with Lightroom 6 (single purchased one) only with the montly subscription.

I have now wrestled with this two days. I've tried to revert the installation back to stable version of 7.2 with numerous different ways, without succeeding. I have deleted everything that is realted to Adobe and Creatie Cloud App and all that s**it, which is kinda annoying, and installed everything again. I went to adobe.com/go/getserial and put the code that I got from the single purchase of Lightroom 6. Downloaded CC App, installed Lightroom CC 2015 (cool name btw). Had to do this couple of times before it got installed. I couldn't use my latest catalogs anymore because they were too new for this Lightroom version which was 6.something. I needed to update my Lightroom 6 to get those catalogs, with all the develop settings, work again. And surprise, it got updated to the 7.3 version. And here I am again, cant control any setting related to colors. They are just greyed out and can't d nothing.

I ask for help. Customers don't wait...
