This could be a minor issue, but I tried logging in to my ADMIN panel to updates some Templates within AC today and my Admin Password no longer works. Checked Capslock and keyed it in very slowly (I'm a somewhat sloppy typist) and still it didn't take.
Anybody had this issue post-upgrade to AC Cert 2014? AC throws an alert message stating that repeated login attempts are tracked, too. I hope that does not count against us for MU somehow if AC thinks a bad guy is trying to log in instead of me...
