It looks like the Logger is trying to connect with the ECU on COM4 and that takes over the COM port from the MTS plugin.
Make sure your Openport 2 is connected.
Stop the Logger (Disconnect button) once loaded. Uncheck the ECU box and the bar at the both right should switch to Externals:
Confirm in the Plugin menu your MTS is COM4 with 1 sensor.
Then select that item in the Externals tab to log.
