Spring RTS Engine

i play on a vista (which i think is a terrible computer)

when i play spring everything is fine on the tester except, when it loads up

1. you cant see trees grass or terrain.

2. any terrain you see is black.

3. the only thing that seems visible is you, your enemy, and any robots or units on the field.

4. and you can see water.

I also need help on the multiplayer lobby thing...when itry to play and it downloads the map. It always fails
plz try to help if you can thank you ^^

Uno: Vista is an operating system not a computer lol...And yes it does suck, I speak from experience...Extremely annoying...
Dos: This problem is most likely caused by your graphics and can probably be fixed by the large capabilities in your settings. I'm not sure what renders the grounds and foliage but there might be a way you can disable effects that may effect the way the components are rendered.
Thres: Be sure to have your Video Card drivers UP TO DATE. This could fix the problem and even increase your FPS.

Well, its all up to date. I still cant figure out how to fix it but im gunna keep trying stuff till i get it working...
