I downloaded the game from SVN and I received this error: "The GL_ARB_multitexture extension doesn't appear to be available on your computer. The game may still work, though - you are welcome to try at your own risk. If not or it doesn't look right, upgrade your graphics card." I'm running Windows 7 and my hardware seems enough to run this game, any ideas on what this means?

Alright! can't wait!
