Upgrade active license from 3.8.2 to 3.8.4?
 

I have an active owned license which I purchased earlier this year. Just now I went to the customer log-in section to try upgrading from 3.8.2* which I am using now* to 3.8.4. I could not find the upgrade option for doing that. As a current customer in good standing* surely I am entitled to upgrade to the current version of the software I purchased less than a year ago? How can I do so?
