Need help with EXEPTION_ACCESS_VIOLATION

[Mudbill]

ATTENTION: System does not support const arrays in glsl!

Well, this line right here seems to be the problem. I actually encountered this as well once, but that was not hardware related. My problem had something to do with the Mac OS 10.9 which wasn't (and still isn't fully) supported. There is a work-around for this issue on the Mac, but if this actually IS hardware related, then I don't think there is much you can do with your current machine. I'm fairly certain Vista should be just fine running this game, so I doubt it's OS related. We even had cases of Windows 2000 running this game fine xP
