Hi, Since i installed the first version of P3D V4, i have a problem with the ATC of MCE When i use MCE with P3D V4 (actually 4.3), MCE normally starst , detects the plane and ATC works normally during taxi and take off. After, when i change frequency to center, approach or another airport (for exemple), the VHF contact does not change on the UI (user interface) of MCE. Of course voice recognition does not work If i choose a command manually with mouse in ATC window menu, so the the VHF contact changes in the UI of MCE. I tried MCE V 2.7.4.2,........... V2.7.6.6 with P3D V4.1...P3D V4.3 - FsInsider64, FsIni, MCE dlls directory (with the good dll64) are ok in he root directory of P3D V4 - Prepar3D.exe run as administrator - no add'ons or dll - basic scenery - It 's the same thing when i use only ATC or when i enable also "call-outs and monitoring " and "Real crew coordination" I have P3D V3 and P3D V4.1 on the same computer (Win 7 64 system with 16 Go RAM) No problem with P3D V3, Multicrew works perfectly. An Idea to solve this problem?? Best regards,
