Running in Simulation Mode

[StarkStudiosWest]

We recently moved across the country and were very careful to dismantle and reassemble Millie and Quilt Path properly. Today I tried using it for the first time. The tablet was connected to our wifi & updates should be current. I put it on Airplane Mode when I began my quilting session.  Everything seems like it's going to work correctly, but when it should being stitching, it seems to be in simulation or trace mode. The needle will go down to pull bobbin, but won't raise on its own. I manually raise it and press "sew" but it glides over the quilt as if in trace forward mode.  I've unplugged and replugged everything, switched it all off and on in the correct sequence. Any suggestions??
