I downloaded the demo of Vue d'Esprit 4. It does not work at all. When I open the program, I get a message saying that there is some kind of error, and Vue has to close immediately. I have several other graphics programs on my PC, including Bryce and Amorphium (demo). I don't have any problems with them. It's a shame, I would love to get Vue, but it's not looking good at this point.
