Game will not launch, repeatable error.

[Plover]

So on my second machine I've been trying to get Regnum running without much success.

Every 1 in 100 tries it decides to launch and runs very well. So something strange is going on...

Every time I launch the log file in LiveServer says this:

This happens after clicking "Enter Game World", where a small Checking Firewall... window would normally appear. Where that window should be is a black box, or a frozen-pixel area which won't update until I force quit Reg.

I've tried re-installing and also getting the data0.sbd from a different computer which runs reg fine. But I'm guessing the real problem is this:

My graphics card is on the supported OpenGL list, although I think the minimum GL version is 1.4 ... Perhaps this problem is that simple of a fix? Could somebody show me how to update OpenGL on my ATI card? I can't figure it out.

Thanks! -Plover
