Scenery objects disapearred after using Simdirector

Hi

I got myself in some trouble by opening Simdirector end playing arround with it.

After opening a prevous saved flight in Simdirector I closed it and since then all objects are disapeared from the airport and the ground isn't flattend anymore

I only got the appron, taxiways ans runway?

Tried to delete  the add-on airport and reinstall it but nothing changed?

I think there must be some kind of exclusion file that overwrites al the existing object. But I got no clue?

Can't find anything in the file structure that is causing such issue?

Any idea's arround here?

Thank in advance

Bert
