Hi John,
Try to do the following (just like on the picture below). Let me know if it helped.
  1. Make sure that the water supply is closed 
  2. Release water pressure by opening the faucet / valve below the saddle valve location and at the highest point in the house
  3. Unscrew packing nut and remove piercing pin / handle assembly from the valve
  4. Make sure that the pin is tightly secured inside the spindle / handle
  5. If it is loose, exchange the valve (grab it with a pair of pliers and try to turn the handle)
  6. If the pin is tight, reinsert it into the body of the valve and turn the spindle until the pin is flush with the clamp
  7. Only after completing #7 screw on the packing nut and re-tighten it
