All of a sudden my Huey calibrator won't calibrate. It says "measurement error" and that means either I am trying to calibrate the wrong kind of monitor (choose between CRT and LCD) or the sensor fell off the monitor during calibration or the monitor is dusty/dirty. None of these things apply - it is just failing when it has always worked before. A quick Google tells me others have this problem but no solution is apparent. I figured this would be a good place to ask for help. Pantone no longer supports this model.

TIA
