When it crashes, what are the last few items shown in history.txt (in the main EU2 folder)?
 
"1697-06-00 : June 1, 1697 : Denmark went with Try to balance things in The Great Northern Conflict. "
Is this always the last line? That would indicate either a bug in the event or something else causing a conflict with it.

Since it's converted from CK, I'd like to know: Does Denmark's capital have a port? Ordinarily it does, but I know crazy things can happen in CK-converted games. The reason I ask is because that event has this line in the "Try to balance things" action (line 619 of db/events/major_dan.txt):
Code:
command = { type = warships which = -2 value = 10 }
If the capital has no port, the game will still try to put ships into the province, which crashes it.

If this is indeed the problem, changing the -2 to a -1 should solve it. (But you should probably change it back once the event has happened.)
