Can't login to our MyBook Live

I am having a similar problem, getting:

Missing Application-Name manifest attribute for: http://mybooklive.device396078.wd2go.com:8081/Admin/webapp/htdocs/MapDrive.jar?v=18

Using Java version 7, update 51

Won’t work on FF or IE, although it ‘used’ to work on FF up until several weeks ago.

Grrrrrrrr…
