[RESOLVED] P3D v.4 load until 100% on Multiplayer then hangs - FSUIPC

[simskunkworks]

Latest P3D v 4.2 version.
It happens that some clients connect in MP and load until 100% then hang and CTD with a fatal error, win event logs registers the error but cannot say which module, it seems the p3d.exe itself.
The weird thing is the error can be worked around loading in SP out of Italy, enter in MP and the move to an Italian airport.
More weird is that do not happens to all systems and worked well before, error began after an WIN update on Wed 14 February.
It happens on a plain system without any add-on.
Any clue ?

Hi,
further investigation has shown that it happens having the FSUIPC as addon,
apologize, forget to mention it, while i wrote "no addon".
No FSUIPC no error, may be Dowson does not have updated it yet.
