As this is a licencing issue, it would be best for you to post a question in the licencing forum here: http://forums.autodesk.com/t5/Installation-Licensi
I hope that is OK.
I am reluctant just to move this thread over as so many of the other comments were not a licencing problem.
Also, check your licpath.lic file (this is not your licence but a pointer to it). Make sure that the first line reads correctly as per the post here http://forums.autodesk.com/t5/Simulation-CFD/Can-t
