I had the same issue. I think it is to do with where you log in from. I cleared my cache and cookies, clicked on the EV Forum, clicked Sign In and just got the same page every time!!
Went to a colleagues machine who uses the forum to, and his favourite was set to the Discussion Forum Home page, logged in there ok.
I would suggest you make the main http://forums.symantec.com/discussions your saved page, log in there and then browse to EV. This works every time for me now.
