Spring RTS Engine

Hey, just downloaded the game a bit ago and I'm not much of a computer person so if this is stupid or easily fixable sorry. When I try to start a single player game it starts loading for a few seconds then I get an error message.
It says "Update Drivers" "Needed extension GL_ARB_texture_env_combine not found". Dunno if this means anything to anyone, but I figured I'd give it a shot I've tried re-installing twice.

I also noticed there are some other topics on this same problem so I'm checking them also. Sorry I didn't find them before this post.

Try following the advice and downloading new drivers for your graphics card. Depending on the brand of your card you will have to download them from different spots, but you probably have an nVidia or ATI card.

Try these sites if you have one of these cards:
nVidia: http://www.nvidia.com/content/drivers/drivers.asp
ATI: http://ati.amd.com/support/driver.html
