I have Prevx licenses on two different machines. This morning I got a popup on my home machine, saying the license had expired along with the protection, instead of the usual "you are protected". So I decided to go ahead and renew, which all went smoothly. Until I noticed that the renewal gave me 570 days to go. Went to My Prevx, and discovered that the actual situation is that the license for machine 2 will expire in 3 days. So for some reason Prevx is unable to send the messages to the correct machine. The key was not expired, and was blocked for the wrong machine. I will just let the other license expire to the free version at this point. You only get to fool me once.
