The problem i have is that i have all the gates showing up correctly, and all the services cars and tugs etc... I also have the overhead gate lights that look over each gate, it is just the buildings except part of the Bravo Terminal near gates B1 to B7
It seems you have the Addon Manager running, but not the Couatl program.
If you don't see the Couatl menu in the FSX main menu, the most likely cause is that the antivirus has blocked it.
If you do see the Couatl menu, but buildings don't show, it means something is not updated so, installing the Stand-Alone Addon Manager AFTER KORD should fix it.
