CTD

[Mad_BOB]

I'm getting a CTD with no error logged - the med2 splash screen shows up sometimes, then the screen goes black and returns me to the desktop. I've tried running vanilla med2 and it works fine.
Changes made
-new buildings added (markets added to castles)
-free upkeep added in castles
-modified number of trade fleets

I checked the 'Guide to Crashes', which suggests this might have something to do with data\unit_models\battle_models.modeldb but i don't see how any of the changes i've made could have affected that?

Thanks in advance.

edit: Nevermind, I'd just dropped a } in the editing...Had been using notepad instead of Notepad++, won't be making that mistake again (i hope...)
