Issue:
Getting an error when launching the simulator:
Can't start communication server.
Default TCP/IP address xx.xx.xx.xx you have set in the option is not a valid IP port for this PC.
Resolution:
Call up Simulator Panel options by right clicking on the avatar and correct the 'Listening IP Address'. It should either be 127.0.0.1 or the ip address of the PC/VM that is running the simulator.
