I have been getting CTDs as a variety of countries when playing the Grand Campaign. I've been able to play scenarios with no problem though, but sometimes I get CTDs after 1492, which makes me think it's not an event crashing the game. I have saved a few of the crashes if you need them emailed. I have a SSI chipset, which required a specific patch for Galactic Civilizations. Have there been any SSI issues for EUII?
