Sorry that you're experiencing problems. When you are trying to access the configuration pages are you doing so using a direct wired connection?
If you are and you're still encountering issues logging into your Superhub please perform a pinhole reset on it and try again. If you've done all of this and the error continues, please post again so that we can investigate further.
