I think Fox said it all. I just bought the 3D World Mag also. I had no problems installing it whatsoever. I don't understand what you mean about the file being to "big" Poppi. All I did was install it and then go to the site address the provided to register it. I then received an email with my registration number to activate the program :o. I have to say, I have had it for 3 days now, and I absolutely love it. This program is wonderful. The render engine ROCKS! My renders in Bryce took up to an hour for a simple scene, Vue does it in 5 minutes (if that long) and I am on a computer that is fast running out of memory. As far as them wanting the scene files, the explanation makes perfect sense. Sheesh...are people suddenly getting too paranoid lately or what?
