via Mylenium, Adobe is Removing their Deactivation Limit:
"The deactivation limit has caused numerous problems and I'm very happy to see it go. As stated above, we should go live on the a new activation server implementation on January 15th that completely removes the deactivation limit. Although deactivation is still necessary (which causes some other problems), there should no longer be any limit to the number of deactivations.
... Note that this affects software as far back as Adobe Creative Suite 3 and Acrobat 8."
