Files in this directory:

# SimConnect.dll and simconnect.manifest

32-bit FSX SimConnect library used to connect to FSX and P3D. Loaded directly by Little Navmap

# SimConnect.ini

This file can be used to diagnose SimConnect problems.

Change the path
"file=C:\Users\YOURUSERNAME\simconnect%03u.log"
in the file to point your home directory or desktop directory.

Then copy the file to your "Flight Simulator X Files" directory (or whatever simulator you use).
This is the directory where the flight plans are stored.

A console will open when the simulator is started and a simconnect.log is created.

Do not forget to remove the file after done with diagnostics.
