This problem appears to be a redirect within Disney at go.com. I cannot get to dvcmembers.com from this laptop and the Disney site tells me "The page you are trying to access is currently not available."
However, my desktop is still on the actual link whateveritis.go.com/blahblah and it works fine and refreshes fine. That machine stays logged in all the time.
Something's fubar at Disney's website. Big Surprise.
