when I select either option it gives me OPEN HANGER DOORS menu..NOT DEPARTURE or ARRIVAL menu..
If you are seeing the CTRL+F12 menu, it means that everything is working (Addon Manager and Couatl), but you might have not installed GSX.
also Jetways do not work...Both are active in ADDON Manager...
Jetways are entirely unrelated to GSX. With "not working", you mean you don't see them, or they are visible but just not animated ? Which parking, exactly, have you tried ? Not *all* parkings have animated jetways (but most of them have).
