I tried loading a flight plan today and received the following message:
Please report the following to OnCourse Software!
frmFPAdjust! (Load) 13-226.
Yesterday it worked fine, today, no. I have not noticed any updates either to Windows 10 or PF3. PF3 version is 3.9.0, P3D V4.5.12.30293
Scratch that, found the error, in the flightplan, PF3 did not recognise one of the way points.
Problem solved.
Thanks
Ken
