I'm now getting a nag screen on my Pro version, never seen this before until today. Does that mean this will happen regularly until I take out a new subscription? Shame on you Piriform/Avast/whatever-you're-called for fraudulently selling the Pro version with a non-expiring, lifetime key. As others have already said, at the time i bought this (directly from Piriform website) around 2012-2013, there was nothing in the email order confirmation that stated the Pro Version had an expiry date.
