IWR1642: Unable to run mmWave Demo Visualizer

When running the mmWave Demo Visualizer I get the following Console Message error:

mmwDemo:/>sensorStart
Debug: Init Calibration Status = 0x7fe

DSS Exception: ../dss_main.c, line 1519.

Connecting through the debugger and running gives a little more detail:

Debug: MMWDemoMSS Received CLI sensorStart Event

Any tips on getting this up and running would be much appreciated.
