Hi again,
If you use the living world AI with AIBTC, and in the case of the FS9 le france, you have to use a sim.cfg instead of the existing one. Have you done that?
I cannot find anything wrong with your 'flightplan'.
If you want several vessels to sail the same route, you will have to open the kml with wordpad, copy the coordinates and rename the KML file.
Example: Say you have three vessels on the same route.
The KML 7200 you save as Lefrance or whatever.
Open your KML file with wordpad, copy the contents and paste them underneath the original coordinates and change the copied 7200 into 7201.
Repeat this for the third vessel and change the 7200 into 7202.
In the boat plan you give your first vessel the route 7200, the second one 7201 and the third 7202.
Now you can compile.
