Pfaff Creative 1473 Thread stuck in bobbin race?

There are four slotted screws on the bottom of the machine that attach the computer to the machine. Undo these screws (they are captive) and the computer section can be moved to the side to allow access to the bottom of the arm. There are two slotted screws that attach the bottom panel of the arm. Remove these screws and remove this panel. You can now access the bobbin race.
