Trouble calibrating new MBA

Just purchased a new 13" Macbook Air and just for fun decided to try to calibrate it with my i1d2. Downloaded the Lion version of i1Display software which I've used previously on my iMac without problem. For some reason, the software does not detect the i1d2 puck. I've checked the system profiler and it is detected there as Eye-one Display. Also tried ColorEyes Pro and it doesn't detect the puck either. Also plugged it in to my iMac and it is detected by the i1Display software. Anyone have any idea why the software isn't detecting the puck on the MBA even though it's plugged in? I still have Lion on the MBA, by the way.

Any help appreciated.

Thanks, Jim
