Well this is a promising beginning... the second mission crashes directly at the beginning with a LUA error. :(
I've got the same problem, crash to desktop on the second campaign mission.

Edit:

From stdout.txt:

CComponent::SetChildrenOrder mismatch: sorted 59, actual 60

Well I fixed my problem by executing Verify/Repair in the "Manage Installation" menu. After that the error is gone. Don't know why.
