I've noticed that none of my FSDreamTeam show up the buildings only the jetways and from checking the VistaMare on the web option which shows all those active sceneries I've have the following error
VistaMare Core FS Interface - Error
The application associated with the request: C:\FSX|http://www.vistamaresoft.com/ cannot be run
I'm sorry, but that module doesn't have anything to do with any of our products, it's a module used by Aerosoft products.
It's POSSIBLE that, whatever problem in your system, which is affecting the Aerosoft module, is ALSO affecting our own modules, which are listed under the "Addons" menu with the "Addon Manager" and the "Couatl powered products" sub-menus.
So, if you are missing both the Aerosoft module (which doesn't have any effect on our sceneries), and our modules, the most likely explanation, is that you have a problem with your FSX installation or you are missing Windows system libraries needed by BOTH modules, so BOTH are affected by this problem.
this thread indicates all the known solutions for missing menu items under the "Addons" menu:
