Enter the email address you bought with. Every licence key on it comes back by email, with the steps to enter it in the app.
The key is also in Loggerhead under Settings, then Licence, on every Mac where it is active. To free a Mac slot, click "Deactivate this Mac" there.
No email after a few minutes, or you bought with a different address? Write to [email protected].
