I'm in the same boat with the rest of you guys... received Navicore a couple days ago, and it refuses to activate. Worse, if you attempt to construct a route, after entering the start and stopping point you get a dialog informing you that routing is unavailable until licensing has succeeded that *can't be dismissed!* (Clicking 'OK' just displays it again!) I had to power cycle my N800 to get rid of it... (all the other keys were ignored).

Anyway... there's a discussion elsewhere on here (I found via Googling) where a guy was having the same activation problem, and he said that at one point he had the chance to use a different Internet connection than his own, and it succeeded so he chalked it up to some firewall or filtering problem with his own connection. However, since so many of us seem to be having this problem, I doubt that it's it -- it seems much more likely that the license activation server is simply down?

EDIT: As with David, as of this (Monday) morning it successfully licensed itself. Yay!
