'Tis not your fault, not at allI know, sorry for the trouble.

Now we're cooking! Didn't consider that until now, but I think that's the problem. The CTDs only appear after a couple of turns of the game (100, 150), i.e. there are more textures (Civs, cities, improvements, units...) as in the beginning. Problem unfortunately solved....your memory can't handle all the graphics, or because one of the graphics is broken or missing, which can also result in a CTD.
Anyway, I'm going to get me a new laptop in 4-8 weeks, so this should only be a temporary issue
