Can't get No Limits to work

I've downloaded the demo,and everytime I attempted to run the simulator it said it couldn't find a rendering context and I needed to update my Driver. I've looked virtually everywhere and I can't get the latest Opengl driver. The editor runs okay, but I really hope I can get it working. Any suggestions?

I get the EXACT same message with my other computer and thats because its a crappy Pentium 2 that can't even run the NL editor without being choppy

Just get a better computer, and it'll work [;)]
