Joffry this is what I imagined, also if on the Quick Reference Card there is an explanation of Mover4 and here you can read that a you can use any previous license. So, i'm going to take a Mover4 for vue 4 professional, because in this way my e-on software suite is complete. :) Do you think, i can buy it form e-on web site in the weekend (download version) or i need to wait until monday ?
