Arduino Mega not connecting to Unity

Issue #39 resolved
Former user created an issue

My project has been working great for months now with no issues. All of the sudden the Arduino Mega stopped connecting to the Uduino Manager. I get the following 2 errors:

The serial port of [\.\COM4] is open in another application. Please close this application first (Arduino IDE ? ) or unplug/plug the device.


UnityException: FindObjectsOfType can only be called from the main thread. Constructors and field initializers will be executed from the loading thread when loading a scene. Don't use this function in the constructor or field initializers, instead move initialization code to the Awake or Start function. Uduino.UduinoManager.get_Instance () (at Assets/Uduino/Scripts/UduinoManager.cs:125)

I have restarted my computer several times and it still does not connect. I have also tried using the Arduino IDE and it DOES talk to the Arduino with the serial interface like normal. I have made sure the Arduino IDE is closed down when running Unity.

Please help me as I am in a time-crunch trying to get this game project across the finish line and this is a catastrophic issue for me.
