I have disable LIRA and PortoSantoX (was other error in log file) and now plang finish, but before with FSX I had a 185 Mb of datafile (PlanG3_FSX) now I have only 66.7 Mb (PlanG3_P3D) infact I see very less airports.
Note that I have 1500 scenery with over 12000 lines in scenery.cfg file (I don't know if is a possible problem with the prg)

Hi,
I also have the same issue, until I used FSX all was ok, but now width P3Dv4 and with the same scenery of FSX Plan-g is freezing during runway writing.
I have attached my log file.
