Makita Air Compressor Mac5200

I've got a Makita mac 5200 air compressor that is suddenly leaking air out the pressure regulator knob (on the knob side). I cant figure out how or why that's happening let alone how to fix. If I screw the knob all the way off, the tank holds pressure, but it's unavailable at the quick connects. If the knob is tightened all the way, it leaks all pressure immediately.
