Using V5.1 of P3D I tried a flight from EHAM to LIML with co-pilot set to Mode 1. After take off and changing to Departure we had some contact with them before the program stopped responding. The wingtip lights on the main PF3 program page were not flashing. I had received a message to contact Departure and had pushed "0" after confirming the copilot had changed to the correct frequency as displayed in the text window. Then that was the end of ATC for the flight. Can you suggest where I went wrong?
Log files attached.
Thanks in advance
