Under 'Expiration', I have a single dash '-', as in NO EXPIRATION. I kept the mail you sent me when I made my ONE TIME purchase, and it clearly shows the product name, customer name, license key, expiration, and my download link. This is DEFINITELY bait'n'switch, Piriform! You lot could learn a thing or two from Malwarebytes about customer support.
