I too bought this product because it was a one time purchase (2015) that I could use on ALL my home computers. It was from Cleverbridge and it was Full feature set, software updates and priority support. No mention anywhere of expiration. This has come up a couple of times in the past when they upgraded and I always contacted them and they reactivated my code. Haven't heard from them this time (other than getting instructions on how to renew my "subscription". Waiting on their answer again and I am hopeful they will honor (grandfather) the users that purchased as lifetime product.
