About three days ago I received a notification from Topaz concerning a free upgrade to Adjust AI if I already had Adjust, DeNoise and one other plugin(don't recall). Since I do own all of those plugins and more I immediately downloaded the free Adjust AI and installed it, no problem. I did do somewhat of a trial run to make sure it was working properly and of course everything was good to go. The strange part of this is that about two hours after I downloaded the free version I had another notification showing the "sale" price with 20% off. I'm wondering if perhaps the first notification for the free upgrade was a mistake and then was pulled. If one has a lot of Topaz plugins I would suggest getting in touch with them and asking about the free upgrade. Of course they would know that I already had enough of their plugins to be eligible for the free upgrade and that might be the reason I received the "free" notification first. It might be in one's favour to at least be in touch with Topaz.
