I double click on the icon on my desktop and it seems to load then it just restarts. I have a ATI radeon express 200 and the game says it needs a video card wi at least 64MB and it has to be either an ATI radeon 8500, 9500 or vista, NVIDIA Geforce4 6100 or vista.
It say that ATI radeon 9200, 9250PCI Nvidia geforce Mx are not supported.
I had the demo some months ago and i downloaded one thing dispite my computer not having enough RAM and it worked, but i forgot what it was.
