No didn't work, I had to retire that campaign. I was actually on turn 374, I don't know what went wrong but I can't continue. Oh well, hopefully we get a little hotfix version soon. I run W7 64 bit and have 8 gigs of ram, the game runs pretty smooth for the most part so I don't think it's a memory issue.

There is also a bug where if you move a group of units (an army), at the end of their movement range, they'll keep the running animation. That makes it impossible to end turn or really to do anything. Just find the culprit unit and click on it, that stops the animation, and the game continues normally.
