It's not the version XP 10.40.
The error occurs with the new apt.dat comming with this version.
There is a new Skydive Dubai Airport in this apt.dat with the ICAO-Code: AE-0003
That's wrong!

Take a texteditor and load the apt.dat from \\X-Plane 10\Resources\default scenery\default apt dat\Earth nav data.
Then search AE-0003 and change this code to AE03.
Thats all!

Cheers,

Your log file show this line:
17:15:27.7 BuildDatabase_Executed: System.InvalidOperationException: String truncation: max=50, len=54, value='Manassas Airport (Harry P. Davis Field)

Ok, string to long!

It was freeware.

Here is the Plan-G_log.txt

In Plan-Gv3.0.6.67, I have the same as arb65912.
After 10 min I shut down Plan-G, restarted and showed the X-Plane datas.

There are only the airports, no ISEC no Airways etc.

I go back to Plan-Gv3.0.2.51!

Cheers and a3g,
