My laptop (Vista 32 bit) has no trouble running Fall from Heaven 2. The game immediately crashes to desktop when I try to load Rise from Erebus. I have tried to load it with user account control on and off, which has not made a difference. My install order is Civ 4 + latest patch + BTS + latest patch + Fall from Heaven 2 + latest patch + Rise from Erebus; no other mods installed. Does anybody know how to dix this?
