First post after looking at this site for years!

I started a game on the minimum video settings (my PC is around about the minimum) and it played quite happily.

I then decided to try and change the settings up one by one to see what my PC could tolerate, but on my first attempt my saved games would not load; they get so far and then the screen goes white and then it crashes to desktop (CTD). Subsequent re-loading of the game and then setting the graphics back to the lowest didn't solve the problem (even after a re-boot).

My last resort to get the game back was to start a new campaign, which then worked just as happily as before.

I have since had the first patch for my game and I am loathe to try and see if I can change the graphics in case I lose my current saved game as before. Any ideas?
