has win 7 been blocked???

Couldn't sign into quicken 2020 (Canada) today, it took me to a "activate your account" window instead. I automatically renewed the subscription 6 months ago and it has worked up to today. I spent 65 minutes on the phone with tech support. We tried everything in his repertoire including new accounts and reinstalling but no luck. He says my subscription is active on his end. His only suggestion was to take my PC to a computer expert (I thought that was quicken tech support) and /or install win 10.
