I'm amazed your PCQ is still running. I started out with PCQ back in the early 2000's and then moved up to MQR that used parts from the PCQ. When you turned your quilt, by chance might you have pulled a wire or cord out or loosened it? It's been awhile since PCQ days so can't remember how it was hooked up. Is the PCQ company still around to give you support?
I even had the MaxThroat but that was useless, more like a door stop than anything. Sorry I can't be of more help.
