another OB3D problem

So I downloaded the program, physX, and Java, but I have few problems with the game. When I try the heavybag, I first see the bag, and then the camera goes crazy. The boxer flys somewhere in the air and then I see only a black screen. I still can go back to the menu after that.

The test works for about 1 minute, but then it crashes.

I have Vista on my computer.

What can I say, please help me!

THEres some problems for everyone with the heavybag..but does multiplayer work for you ?
