Hello, I am running Windows 10 64 bit and it seems I am unable to unscrew the screw to open the Call Button box. I've put the knife in the screw and see a hint to press the left mouse button and an arrow pointing up, but when I do the knife jiggles, but the screw does not retract. Am I doing something wrong?... Don
