Those are not even the FSDT Zurich jetways, but the default ones so, there's no scenery at all.
It's possible the Live Update got blocked ? There are some defective antivirus that flags it as a threat and, if the Live Update cannot complete, the scenery won't show. Configure the antivirus to add the whole Addon Manager folder to the antivirus EXCLUSIONS, then run the FSDT Live Update again, be sure it completes with no errors.
