Running the latest VM & VS 2015.  Getting this odd set of complaints (below) with each Build.  I just run the Build again, and they go away, and all is well.

The only "new" thing is I'm using a different FTDI cable - the new one from AdaFruit with the chip in the USB end...

Just wondering what might be up.
