Rainbow Six : Vegas (Image)

[Haunted]

I've read everything posted on this thread.
I have a problem starting Rainbow Six Vegas, and I haven't found
A real solution around here.
So I'll ask in a more detailed way, and perhaps help other people
Which have the same problem as me.

First of all, my machine:
Intel Pentium 4 3Ghz
1GB RAM
ATI Radeon 9600 128MB

My problem:
I've installed the game, updated to 1.02 patch, and replaced the exe with the crack provided.
When I start the game I get the credits of UbiSoft and Unreal Technology
But when the loading screen comes with the runing soldiers above it just freezes.
I still hear the music, but the loading is stuck. And the soldiers above aren't really running...
I looked on the computer's red lamp, and its not working.
Like the computer is not proccessing anything.

After a couple of minutes the loading screen just crashes back to the desktop.

Someone here mentioned that this game doesn't support some of the video cards
And 9600 was included.
Its been said here that this game requires a pixel shade 3.0 video card or something like that.

Which leads me to my question:
If this in fact the problem (and it can't be managed by any software) is there
Any other way to make this game work without buying a new video card ?

I've tried everything mentioned here, and would REALLY appreciate any help.
