inconsistent authentication code error

I have moved my pgf 6.1 installation to a new hardware platform and as a result had to regenerate keys. No surprise there. I regenerated the keys and am getting the following error for each feature:

20:28:41 (pgroupd) Invalid license key (inconsistent authentication code)

Any ideas?

Hi,

Please contact license@pgroup.com for you problem.

Thank you,
