Have you tried to enter your name and email address to PowerTools X's My Account tool? It should automatically download and install your license.
The Contact Us page takes one to the Download My License page for a few reasons. Firstly, many people contact us asking what license they own, are they entitled for a free update and so forth, and the answer to these questions can be found from the Download My License page. But also, the Download My License page checks each customer's license level and offers VIP priority support email address for our VIP customers.
