Recently my RAID0 array died so when rebuilding my machine I decided to take the plunge and install XP pro x64. Since then I reinstalled GalCiv2 and all the expansions. Everything seems to run well (original game, dark avatar) except twilight. When I click on the icon part of my screen goes black and it just sits there. Before the crash/rebuild of my system on my XP pro 32bit OS it ran fine.
I run other games like civ4, vampire:bloodlines and such ok as well under my current OS. So I know this is not a system wide issue.
Any input or help appreciated
