No worries - just send us a ticket in the support desk here​ and we'll take care of that for you.  You'll also need to send in your wp-admin details, the email address you used to purchase the editor with and your license details.  We will then activate it for you manually.

In 99% of Wordpress installations, the license can be activated automatically, however in some rare cases the server is set up in a way that won't communicate with our license server, and that's why we have to do a manual activation.
