Here is my acknowledgement:

End Date: 3/22/2021
Renewal Date 3/22/2021
So today I try to get what I paid for, and, wouldn't you know it, I cannot login. The first attempt locked my account. This is very BAD behavior. I need a sentient human being to get my Quicken working again or I will complain loudly. Having no direct customer service is stupid, to put it bluntly.
Just now I downloaded the Install.exe file posted by Sherlock. After backing up I installed it. Right away I was able to log into my account, and Quicken now performs the One Step Update from my bank.
What would help is a FAQ for us old people that says something like "There is a cookie in your computer based Quicken that will automatically verify and enable the Quicken subscription." I was expecting something much more complicated would need to be done.
On the matter of telephone support, the number appears on one of the screens during updating. I guess you can't see it until you pay?
