pid vi's are missing

The pid pallettes in labview are missing, how do I get them back?

Was the palate once there and now it's gone? To get it back, pin down the functions palate (right click anywhere and then click the little pin in the upper left hand corner), go under Customize->Change Visible Palates and recheck the box for the PID palate.
