Spring RTS Engine

When i try to run the game or the test, I get this error: Update drivers. Needed extension GL_ARB_texture_env_combine not found
I run on vista. AMD Turion64 x2. ATI Radeon Xpress 1150.
Why? =(

ATI+Vista == bad OpenGL support.

Just keep updating your drivers when new ones come out and hope for the best.(Dont forget to uninstall drivers before installing a newer version)
