I have no idea why it happened to me and not to others, but I bought Vue 8 Studio and I'm very happy with it.  I had to revert from the 8.4 update though, because it caused endless crashes.

Cornucopia3D is another story.  Every time I try to buy something that states it's okay for Studio, I am told I have to enter a serial number for Vue 8 Infinite if I want to buy it.  They're impossible.
