-btw, this is with the full install over new game and all that.
I loaded the game, and your CTD is due to one of two things:

1) Playing a v.80 game in a v.81 install, or

2) A v.80 map.rwm file in a v.81 build

I know this because when I load the game in my clean v.81 build, it shows up with the Blue Baktrian Border in Belgica. And that's a sure sign of one of those two problems.
