I've also just lost my second campaign to CTDs. First time was my GB campaign which died during the AI's turn on 1785 regardless of which of the 4 saves I tried to play from. My second dead campaign was my Prussian one, which seems to have corrupted saved games as it white screens from the last 2 saves from 1739 and 1740, and as I'd done some spring cleaning on my hard drive, the previous save is from 18 years before - I can't be doing with playing out an alternate time line from that far back. I was enjoying that campaign too - I'd just finished off Poland and was considering whether to turn my energies Eastward into Russia, or absorb Austria into my expanding empire.

Bah.

So, do I start a new campaign, or wait for the patch? I've not seen anything to say whether or not it's save game compatible.
