I have posted this over in the FSHost forum, but seeing as how the previous threads are 2 yrs old. . . .I'm not sure it will even be seen by the right people. . .so I'll ask here as well. I was flying in MP yesterday and was unable to see the other persons aircraft (we were both flying the same airplane. . .he in Ver1.4 and me in Ver2.0). Anyway, I highlited his name in the chatbox and selected to "change players aircraft". Only problem was, no aircraft showed up in the selection window. I have mostly default P3D aircraft right now, but I also have a few FSX portovers (which we were flying). Nothing was visible though, not the default airplanes and not the portovers. Does anyone have any idea why that would be the case? I have a registered version of FSUIPC installed.
