This all started a few weeks ago. Not sure what has caused this to happen going to MyBookLive. I have another Mac on the network and that one works fine. Not sure if having mulitple Mac s going to is the problem. It has been happening since that last two versions of firmware, even after the update this morning.
Both Mac s running latest version of OS X LION. The one that is failing is my mid-2010 Macbook Pro, new 2011 Macbook Air is fine.
