3rd Gen Heat not Running after new install

[CardindalNest]

I used a C wire adapter (connected to Rh & C) since I did not have one (see photo). The Nest powers on and I  successfully installed and sync'd app to the wall unit. I set to  heat, but nothing happened....heat and fan tests, nothing...I put back the old thermostat and it worked as before. Any ideas?
