I have a new installation of MC 8.6.4. This is a 3-year pre-paid subscription, but in the App Manager it lists the renewal date as 12/8/16 on the Licensing Tab, though it does say 'Activated', and on the MC splash screen it shows MC as expiring in 33 days. I did sign in successfully to the App Manager and on the Account Tab I can see my version with the correct expiration date. When I started MC for the first time I got the activation dialog and chose to activate electonically, but when I clicked the OK button the dialog just disappeared, so I assumed all was well.
Why the expiration in 33 days?
