I found I counld not access my brand new MyBookLive remotely (Win 7 64 bit) on either Internet Explorer or Firefox as the certificate was untrusted (error 1244) and would not install in Windows.
Using Chrome, however, one can click through a series of warnings. This forces the certificate to permanently install in Windows.
Subsequently, one can click through warnings and access your MyBookLive with either Internet Explorer or Firefox.
I was able to reproduce both the problem and the fix on another computer.
Hope someone else finds this helpful.
