What you should do is give everyone more information about your system. What OS? What CPU? What amount of RAM? Don't ask a general question like that and expect a vast amount of help.

I have a gateway 1000mhz 256mb ram geforce 4 64mb video card, running windows 2000 Pro. Now does that help?

Do you have the latest Nvidia drivers installed?

I just looked around on the net a little and found a review of this game from 1998. If you're trying to run it on Windows 2000, that means you're most likely running into a compatibility problem.
 
Best thing to do is make sure you're on the latest Windows 2000 service pack and all of the compatibility packs are updated. Then, right-click on the shortcut and choose properties. Try to choose a compatibility mode for the game (most likely Windows 98 ).
 
If the game *still* doesn't run with compatibility mode on, you're most likely out of luck and will not be able to play it on 2000.

I tried going to the game creator's website ( www.ssionline.com) and discovered that it is down... I ended up at a domain park.
 
So that rules out any compatibility patches from the game creator's website - you might find a compatibility patch by searching Google, but I have this bad feeling you're not going to be able to play it on 2000.

Are you running XP? There is a thread already started about the solution for this game & XP users at:
