mate i got the same graphics card you do and it worked for me yesterday.
I know the guys have gone over this but what you need to do is:
* Download that 20MB file from the link barmyarmy gave on the other thread.
* If you have something like DAP or NetTransport you are going to have to disable them or uninstall them temporaraily as the download wont work if you dont.
* Before you start to install it, go to control panel and add/remove programs and delete any NVIDIA driver thing you see.
* Turn off your virus scanner (if you have one)
* Install that file (the one barmyarmy linked us up with)
* It should work
* With changing the settings to windows 98 in the compatabilty tab, i think that could possibly help too. I changed mine to Windows 98 compatatbility, and teh game worked last night. So this morning i tried changing it back to normal compatatilbty , just to see if it would work, and it did.
