Hi, I purchased PF3 this weekend and am experiencing the FPP error when loading a flight plan (I have not been able to connect to the flight sim yet as a result). This happens for flight plans I have created in P3D v4 as well as those downloaded from https://flightplandatabase.com
I have run register.exe as administrator and also validated the install with no errors. I also downloaded version 4.82 of MakeRunways.exe and ran it as well. I'm out of ideas and I haven't been able to find other possible solutions (note I haven't uninstalled and reinstalled as I had the same problem with the Demo version and just chocked it up to not having the fully paid version).
Clean installation of Windows 10 64 bit (v1703)
.Net frameworks 2, 3, and 4 installed
no antivirus installed
P3D v18.104.22.16886 (i.e. hot fix 1)
P3D v4 SDK
FSUIPC with wideserver (registered) v5.103
ORBX (base pack, openLC NA, several NA regions such as southern CA)
Several Carenado and Accu-sim A2A planes
PFC DLL 2.41 (for PFC console)
PFCHID 1.49 (for PFC console)
No other flight simulators have been installed.
I have attached the compressed log and route files.
