yes, this is what we are talking about. It would save us almost half the price of the upgrade. I agree it shouldn't be allowed in a perfect world but the upgrade price is higher for vue 5 infinite to vue 6 infinite than it is for vue 4 pro users to upgrade to Vue 6 Infinite. That doesn't seem fair and "shouldn't be allowed" either. Why such a price difference. Is this a mistake. Well, i don't want to focus on it anymore. Vue 6 infinite looks good and this plus the node lock is killing the joy. Maybe I'll downgrade from vue 5 infinite to Vue 6 and save some money. But that would be odd, too.
