Follow those steps to post your dxdiag, though I reckon it's a lost cause.
I'm 99.9925% sure that your "GPU" is the problem. The x1200 was a terrible card six years ago. Today, it's unlikely that any game would support it, even if it did have the power to run it. It's sort of like... trying to power a Cessna with a 50cc dirtbike engine.
Frankly, I'm surprised that you were able to run the game at all.
Long story short, I doubt the devs would be able to make BR run adequately on your computer.
