Ah - so it's an old i1 Display.
We have not tested them for some time, so there may be a bug... but unlikely...
It should work, so long as it is not a 'special' version (from HP or similar)
But, the reason we have not tested them is they really are not at all suitable for accurate calibration. You should upgrade to an i1 Display Pro as a minimum.
Do you have any other 'calibration' software running - such as from X-Rrite or Spectracal.
Some such software will aggressively take control of amy attached probe, and not relinquish it for use by alternative systems.
Also, can you attach a screen grab of the selected probe options?
