Illustrator 2017 Muse 2018 "Renew Your Subscription" warning in CC

Well, I can say that the experience had with Adobe Support was not good.  The first session ended abruptly and without warning.  The next business day I sought to reestablish the process, and to a certain extent some headway was gained.  Thanks to the remote assistance of a knowledgeable tech, I was able to get Illustrator 21.0.2 to open, albeit as a TRIAL version only.  Muse 2018 would begin to load but crashed mid-splash screen.
The next business day I sought to have the Illustrator Trial converted back to my subscription plan (which it had been part of for many years) and get resolution for Muse 2018.

Things did not go well. It became obvious that this person did not know how to do what was asked.  Not every tech can solve such matters.  I began to hope my case would be handed over to someone else.  At one point I let the remote tech know that I needed to step away from the workstation to assist a client.
On my return could see the remote tech changing my internet proxy TLD and LAN settings.  This alarmed me greatly.  We know that the Adobe program settings and preferences are in the Adobe folders such as OOBE, NOT in the internet settings.  I demanded that the tech cease at once.
During the session this tech reiterated that Adobe offers the current and one previous release for CC customers and that I should use them.  All others are no longer supported.  I get that, and to remind me of this repeatedly is like a ‘Teacher’ slapping my hand.  But here is the real issue…these apps were working one day and gone the next…without warning.  I asked for a transcript and was promised it would be in my email.  That did not happen. Thankfully I did copy it from this workstation before closing the support window.

What is my takeaway?

I no longer have trust in Adobe remote support.  My expenditure of time to have an issue fixed that was not my doing is now at just under 4 hours.  In summary, I received ineffective and untrustworthy customer service (bad business acumen).
I can live without Muse 2018 as the last Muse-authored site was being rebuilt in WP (just that the reference site is now unobtainable). I can live without Illustrator 21.0.2 (the Trial ends in 2 days) and its ability to open certain CAD files.  So, I now need to go into AutoCAD and bill that client for more time.  You know…I keep Illustrator CS4 on one workstation for its sole ability to open and work with FreehandMX files.  That is another story in itself : )
Point being – we use whatever tool is best to do our job well.  

I should not need to fight for the tools I pay for.

do you have a teams, education or enterprise subscription?
