Hi Bob,
Same problem here. I can see all my local flights in 3D, but not the Network Flights.
That would suggest its a server problem rather than a 3D plug-in problem.
I have an NVidia GTX260 Graphics card, and have had nothing but problems with 3D. Airnav gave me lots of suggestions (reloading into different directory, run as Admin etc, new drivers etc, but its never been fixed.
I have even tried installing Windows 7 on a seperate boot disk, along with a complete reload, and I still get 3D models either non-existent, or disappearing over time ( I only see white stalks all over the place after using for a while). I constantly have to keep shutting down Airnav application, and reload it. The models are there for a while then disappear gradually.
To be honest I have given up. (and I can run FSX to the extreme , and all other applications with no issues).
The other issue I have with 3D is that I can rarely (sometimes impossible) select any aircraft with 3D interface, to get the 3D glideslopes. Although I can select aircraft fine on 2D. I reported to Airnav on a support ticket , and still no fix.
I would be interested which graphics cards Airnav users are using , and how successful and stable there graphic cards have been on 3D Airnav. The reason I ask is that I see no other option than to invest in a new graphics card.
I have added my PC spec:
Windows Vista x64 Home Premium
Intel Core2 Quad Q9650 @3.00ghz
NVidia GTX260 (have tried all Nvidia drivers inc latest , to no avail)
8GB RAM
Airnav v4.03 , and the latest database released.
Subscriber to Airnav Live Network. (Yes Im a mug !) But I believe in Airnav...

PS Hurry up with MLAT so I can see all my 100's of Flybe flights...Thankyou. ;-)
