Hello, I too am going to purchase Vue.. Ive got the 30 day demo and really like it! I called e-on to purchase and The guy on the other end of the lines said i had to purchase Vue 3 ,then Vue 4 ?? Duh , this doesnt sound right.. purhaps there weekend purchase guy isnt up on the software? At the website in requirements it doesnt mention anything about having Vue 3 to purchase 4.. maybe I should call on a weekday to order? regards PE
