Hope we can get it up and running.

Thanks for the response.  The program just does not save.  After I click Export and then the FSX pln option, it simply returns to the main map screen.  No pop-ups, windows, options or advisories!

It's got me beat.  The log just shows that it doesn't proceed with the save but gives no reason for it.

Something must be causing the Save dialogue box to not show up... or any part of the Save routine.

I have scanned the C: drive for *pln files and none found except in the FSX missions.

Made several flight plans and could not export any of them at all.  Reloaded v3.1.1 three times and no joy.
Could anyone give asvice
