I ran into the same situation with the folks at World Builder. I was intrigued by the prospect of being able to animate "everything" in a scene, water, wind-blown trees and grasses, etc. I bought the 3.1 Standard edition over a year ago, and though the website and the re-seller said it will run on Win98, it won't. They never answered E-mails either, and when I asked a question about the program in their website forum I was chided by one of the company spokesmen for running an "obsolete OS". I felt so let down and discouraged by their attitude and arrogance that I de-installed the bug-ridden piece of &#;*%!!.

So even though I have two new computers and they both run XP, I am not going to give them a second chance. Anyone want a registered copy of Digital Element's World Builder? Maybe I should sponsor a contest of my own, with WB as the no-prize. The ONLY good thing about buying WB is that they introduced me to Renderosity, which lead me to this forum, and thus to many good friendships.
