It behaves a bit strangely on my dual-core at work.
Most of the time it just hangs after "loading", sometimes it crashes, sometimes it works.
Probably some threading-issue?

Very possible.  The program multithreads and I wasn't able to test it on a multi-core machine.  My machine at work is quad core so I could possibly try to fix it, but I dont think I'll find the time :(.

This unfortunately doesn't work for me on the work PC.

I get a "loading..." message for about 15 seconds (flashing), then a black screen. 

The screen shot looks interesting.

Out of interest benny and voltage, what are your computer specs.  That might give me a hint to what's going on.

I tried it on some GeForce at my working place running Win XP.
I can tell you the exact gfx card model next week.

After upgrading dx it worked!

Cool.

It's not easy to gen natural trees like that from scratch. awesome job.

I can't wait to see some leafs on and generated wood+texturemapped version.

Thanks for the comments.  Indeed it took a lot of tweaking and iterations to get them to start looking natural.  What I finally settled on for the demo was to layer several iso splines ontop of each other for each branch and slightly perturb the node positions using a gaussian distribution.  This gave the branches a more natural shape rather than looking like pipes.  I also used combinations of gaussian distributions and white noise the generate the positioning and curvature of the branches and used repulsion forces to seperate the branches out.  It took a lot of tweaking but I think it was worth it  ;D.
