I have tried redoing the FSDT updater numerous times to no avail.
I am using GSX 2 with the LevelD-767 in FSX. I have tried several different third party airports including the New York Airports JFK and T2G LFPG and my home airport ImagineSim ATL. Most things work well. The old problem with a cargo loader appearing when it was not supposed to is gone. The pushback works well and I like the new voice (think about adding national accents for different countries). The airport configuration tool works very nicely. The F5 gate at my JFK has a little gap between the gate hood and the plane, so I can peek in and see the passengers walking on to the plane, so that feature is working, too.
But I have two problems that others have reported also:
I cannot reset - Couati will not reload, even if I turn off all anti-virus protection and even after reinstalling GSX2 or redoing FSDT updater.
Passenger loading and unloading never ends - it just keeps going, and going, and going. I cannot use the new system for changing the number of passengers because of how I use ATC software (Radar Contact) and AdvText display. You need a system that doesn't interfere with that. But even if I put on the plane a very light load (using TOPCAT), the problem persists.
