Please click "I HAVE AN ACTIVATION CODE" and then paste the code into the box displayed and click apply. Credit card and PayPal fields will disappear and you will receive a confirmation message the code has been applied successfully. If you get an error code after application, please email us with a screenshot and your code number and we'll get you up and running as soon as possible.
