I'm glad you were able to sort out the solution (or maybe it sorted itself out?  )

Something to watch out for with the Wireling system that happens rarely - the pins on the inside of the connector on the Wirelings or the Wireling Adapter Shield can have the pins bent when the wires are plugged in at an angle. It's always a pin furthermost right or left, so it could be either the GND or INT pin that isn't connected when this happens.

If this happens - you can straighten out the pin carefully with some thin tweezers and some magnification (or good eyes)
