I just installed PFE3 and updated it to 3.1.7.
Thus far, I have not been able to compile/process a single flightplan. The "Processing flight plan screen keeps on running". I can make it go away by double clicking, but afterwards the PFE program is unclickable. My flightplans are created with PFPX in the .pln format and used to work in the old PFE. As I read in the manual that this process should only take seconds, I guess something is seriously wrong.
So I followed a few tips from this forum, the last one was reinstall with AV turned off, but no avail...

What should I do?
Kind regards,
