Clusterball on Win2k crushes

[Wolfenx666 0]

After starting Clusterball, I always get the message can´t swap buffers.

 

What does it mean, and how know to help me?

 

I´m using a Celeron II @ 850 MHz, ASUS P2BF, DirectX8 Beta (Which works fine until know with every game!)an a Diamond Viper V770 TNT2 Ultra
