I have received a new motherboard (second time in the last 4 monthes) of my MBP. Now I am asked to set my product key but get the "maximum number of activations" exceeded message when I start parallels: I have seen the KB article on uninstall/re-install to move to a new MBP but could not do so before the system aborted and needed the replacement ;-) How can I move the activation or otherwise re-activate?
