Hi,
Looking at some other posts for help. I also ran the update from the new installer and have similar problems. The jetway and ground crew work, catering trucks are dispatched. Problem starts when the fuel truck arrives at the a/c. I often use Aerosoft Airbus so refueling function used to work. After truck arrived, all GSX functions cease to work; no command menu (Ctrl F12), no restart of Couatl/rebuild airport cache. Only way out is to log off FSX completely. Next, I tried to disable refueling in the settings. Again, all GSX loading operations worked until fuel truck arrived.
Please see the attached Couatl,log file. Looks like some animation file is missing? Hope this helps.
Best regards,
PJM
