Moving Avid subscription to my macbook

Hi there,

I'm moving my computer from an imac to my new macbook...and my Avid subscription with it.

I set up my new macbook from my time machine backup.

Then I deactivated my Avid subscription on my imac - restarted my macbook, and went to activate it there.  It was already activated, but when I tried to deactivate it came up with:

Failed deactivation: 0 Deactivation OK. No record of this device was found.

Any ideas?!!

Thanks
