	I'm using VS 2015 and this tool worked like a charm until recently. Now, every time I upload code, and the Serial monitor opens up, I get the message: Unable to load serial viewer on COMXX object reference not set to an instance of an object. On a new project, the same code works just fine. This project, however, is part of a bigger Visual Studio Solution, and would like to keep it that way... What's happening?

	It sounds like you have set some debugger properties that aren't valid and that visual micro needs to show a better error. Save me asking lots of questions please zip and email the _vm sub folder below the project. Thanks
