I bought Vue 4 right when it came out, bought Vue 5 right when it came out and upgraded to Vue 5 Infinite before it was released. I got this e-mail this morning. Unless I'm reading it wrong...it states I can upgrade from Vue 4 to Vue 5 Infinite for $199 (see line that says "Did you know? As a Vue 4 user, you are entitled to special discounted upgrade fees: you could get Vue 5 Infinite for only $199 (SRP: $599)!")
