repeated crash: GalCivII - Twilight of the Arnor
I'm on a clean install of Vista on a notebook and I've played several games of TotA on tiny, small and medium sized galaxies. Now I'm several hours into a large galaxy game and the game keeps crashing when I hit the turn button. I loaded a previous point (autosave) and it keeps crashing on the same turn. So I saved the game one turn before the crash. Now this savegame won't load, it crashes the game.
What can I do to continue the game?
And how do I prevent something like this happening to future games?
