I did a clean install of the latest FSUIPC 5.124 but there's something strange going on. I load up the PMDG 737 at FlyTampa EHAM (gate D47) and once the scenery is done loading, just as the plane systems start loading from 20 sec (I think), it get's interrupted. If I call up the FSUIPC menu from the Add-ons, it opens but with a few seconds delay. As soon as I close the FSUIPC menu, P3D crashes instantly. I went one step further and disabled every .dll and .exe entry in the .xml in order to reproduce the cause and the only thing that, once it's disabled didn't cause any issues with the same or different scenario is the FSUIPC5.dll in the dll.xml entry. Plane loads completely, views can be changed in ChasePlane etc.
I'm not saying that the FSUIPC is the main cause but something is definitely interfering with the FSUIPC module and I can't find what it is.
I have already zipped the FSUIPC5.log and I can upload it here if needed.
