About the extension of the demo version of Hexagon, you can email the european tech support (europe_support(at)eovia.com) and request it. You will have a new serial number, for 15 extra days if I'm not wrong (but no more extra time extension after this one). By the way, it's actually holidays in france, and I know that the tech support won't answer these request until friday 18th Thomas http://www.eovia3d.net
