Open the Centurion software with your hardware connected. At the top, on the title bar, the license state should be visible. You can refresh and confirm this license by clicking the "License!" dropdown and "Check/Update License button".
If the license shows that it is a Centurion Super Pro that is 2 or more years less than what is offered today, a Max Year license update is best. If it is only one year, or denotes a different Centurion Product, this is not the correct license.
