The upgrade email says:
Existing Gold/Platinum/Professional Members - Have automatically had a BeerSmith 3 license installed in their cloud account for their current term. I will also update the accounts once more before the launch date. No action is needed on your part, and you do not need to pay separately for an upgrade.
When I log in and follow the links to upgrade, it sends to a page where I asked to pay for another subscription to upgrade.
