Activate your licence

Your licence is tied to one installation. Enter the entitlement code from your purchase email together with the installation ID shown in SeedCrypt, and you will get a block of characters to paste back into the app. That is the last time the app touches the network — verification afterwards is entirely offline.

Your purchase

From your purchase email. It identifies the purchase — on its own it unlocks nothing.
The address you paid with. Asking for both means a leaked code alone cannot burn your seats.
