New intel quad 2 processor w/vista. Usually playing custom game against three other civs on standard or large map with only conquest or domination option with unlimited time. Get well into game (approx. 200-300 turns) and message appears (causing game to be lost) saying error has occured which Microsoft will investigate and notify if fix is available. This never happened under xp, and needless to say-never heard back from Microsoft in spite of several instances.

Welcome to the posting side of Civfanatics :band: :dance: [party]

does the error message give you any more information? Also what memory and graphics card specifications does your machine have?
