Crashes on startup

[T1migi]

I played spring yesterday, and it worked fine. Now it keeps crashing everytime it's done loading. It does this with every mod and every map. My graphics settings are all as low as they can go. I've checked the forum and couldn't find an answer. Anybody know how to help?

try to get better drivers... crash happens in the driver code, not much we can do.

[T1migi]

I'm having a bit of trouble finding better drivers.
And why'd it work yesterday, and not now?

Edit: I've done some things and now it keeps saying GL_ARB_texture_env_combine not found. I checked the FAQ and everything is fine, but it keeps giving me the error. What do I do? I've updated my drivers.
