I have a craftsman radial arm saw and I can not get the blade to move up and down the arm. It is frozen. How do I get it un frozen ???

That's the only thing that I can imagine would cause the symptom you describe other than obvious physical damage to the arm/carriage or a ton of rust - either of which should be obvious to the casual observer.
