MAX - export nce file

[Yutao1]

This bothers me... I tried to export some configurations to a nce file, so I can load to another computer, but in the Export wizard, I couldn't see any virtual channels and DAQ's which I can select to export. Definitely they are there. Attached a snap shot to show the problem.

I have another computer, MAX Export works OK as normal.

I restarted my computer, re-install DAQ-mx, no help.

any ideas or solutions?
