Purloinius, Vue 4 Pro was NOT an upgrade, but a sidegrde for Vue 4 users. There is a little difference:-). Vue 4 Pro is a stand alone program. E-on has never ripped off anybody. Contrary they are the most friendly and helpful people to us customers. And this since always. A friendly language to write to them in explaining point by point and in details your problems and you will get a friendly and clear answer. Guitta
