Depends on when you bought your Pro version. The suscription is only good for 6 mnths and just recently been offered for a year. So if its been longer than 6 mnths your e-mail address won't be in the data base any longer. If you want the updates and "e-mail support"
that they offer, then you will have to re-purchase.
Or Use Basic which is Free. Not much difference between Basic & Pro.
