Hi John.

I haven't had any trouble with the Beta download. It runs fine on my computer. My processor is a AMD Athlon 3000+, 2.2 GHz and using a Connect 3D RADEON 9600 series 128M video card. I have seen problems with new the G3 add-ons 1 and 2, if you don't have enough RAM. I have 1 gig and wish I had more. Being a BETA version, there may also be some hardware compatibility problems they haven't worked out.

You might try re-downloading if you still want to mess with it, but it's mostly eye candy anyway. There are some physics changes though. I guess the neatest thing I saw was that parts fly out of the crashes now. It doesn't just come apart like before. Not exactly a requirement for learning, but neato!
