Thanks I tried again with your instructions:_
Option 1: Look in your ..\Civilization III\Art\movies\ folder for a file called "Race.BIK". Rename this to "Race_Old.bik" or some other name. Make a copy of "intro.BIK" (or even "security_briefing.bik") found in the same folder. Rename it to "Race.BIK". Now you won't get the space race movie, but hopefully the game won't crash....
this work in the vanilla civ 3 but the game still crashes in conquests expansion,
there is a "Conquests.bik" file & "Victory_Movie.bik file" is the p[rocess similer to above?
