When I want to edit a PDF, it gives "more info", then I have to buy a subscription?

I have a stand alone version of Adobe Acrobat DC Pro.  When ever I try to use it, it sends me to a "more info" area, and requires a subscription.  Adobe and Microsoft have both worked on this.On Windows 10 they even had me log into the hidden Administrator  sign on, but that doesn't work either. I have run all virus/malware scans I can think of.   I've been working on this since November with Adobe and Microsoft to no avail.  HELP!
