I have just install FS2Crew v1.6 for PMDG 777 Prepar3D v3. I have run into a problem with FS2Crew will crash Prepar3D v3 when enable when i click on the application Vpilot to connect to Vatsim. When I disable FS2Crew PMDG 777 Vpilot app will work and connect to Vatsim. There was no problem with FS2Crew 1.5 working with Vpilot on Prepar3D v2.5. With Vpilot app the connect button is gray out with fs2crew 777 enable. Disable fs2crew 777 Vpilot connect button becomes active.
