hmm guys... I'm getting again and again the issue with all shields deactivated and a license expired message after each reboot, always fixed manually as I described above but it happens again.
I installed from scratch, so an upgrade problem can't be the issue.
edit: the behavior shield doesn't seem to do more than it use to (on W7/64), not that it's just passive as Vlk described, but it still doesn't scan anything, probably still no rule sets like before.
