Ok, here's the deal, I have a machine that I KNOW can run this, (duo 2.4, 2GB DRR2 800, Nvidia 7950 GTX 1GB), I am running Vista Ultimate x86 (aka 32 bit), and GalCivII DA Gold Eddition. When I play this game in Vista, no matter what I do, it, seeming randomly, locks up. I've tried to pinpoint the reason it happens, and cannot find one, the game just locks up. My system, however, does not, I can still move my cursor, and if I hit esc, and then minimize it (via windows key) and then maximize it (via taskbar) I can *sometimes* manage to save my game, or if I gave a mouse command, do PERHAPS one or two things, (like start a new research track). Sometimes I can do this, sometimes I cannot, all the time the game locks up and will not respond, except for the ability to winkey it, move my cursor, and alt+f4 it. When it locks up like this it just freezes on the screen it was on, (any screen, with or without turn button, research screen, galaxtic map screen, whathaveyou). I thought at first it was because it wasn't updated, so I updated it, and got perhaps 30mins to two hours, (I really don't know, but it was a while, and a huuuuge deal more than I've been able to play continuously for a while). I thought the problem was fixed, but after leaving my pc for a while, and comming back and playing some more, it started having this same problem again. And no matter what I do, it WILL NOT go away. I've tried it in a standard account, admin account, in XP SP2 compatiblity mode, I've tried restarting, restarting and letting the pc sit for a little while, low graphics settings, high graphics settings, from a saved game, new game, auto save every 14 turns, auto save every turn, I'm at wits end, totaly out of ideas. Can anybody help me? Please? I LOVE this game but it is IMPOSSIBLE to play it like this. And btw, I have not noticed similar problems in any other programs that I can think of, but I haven't been doing much gaming other than GalCivII as of late. Thanks for your help in advance, God bless. Dabb out.
