Spring RTS Engine

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...

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...
