Try loading the default flight at Seattle and when you're on the runway select 'go to airport' and go to Portland. See if that works ...
As Flight Environment does not add anything to your scenery.cfg I don't suspect that the issue is there.
Other than that, I really have no idea how to fix the issue other than removing FZ2: Portland and reinstalling it.
