VuePro and Vue 5 both have customized versions of Mover 5 on the installation CD. Mover 4 simply will not function here. If you have purchased Mover 4 though, then you have a liscence for Mover 5; just install the MoverX on the CD, and register it with the Mover 4 number. The app will probably also ask you for the number of the Vue version you bought Mover 4 for...they key off each other for verification purposed. And I want my Infinite Too......! I also want to see a Phoul-crafted teaser or demo of just what Infinite can do... (drooool).
