I've been having the same issue as the above snitchseekers, but I found a way to get on by going to an email of a notification to a reply to my ff. I clicked on the link provided and from there I can navigate everywhere else so far without going advanced. Oh, and thanks for the update, sweetpinkpixie.
So, I made a mistake
I can't navigate any of the top places: Home, News, Forums etc, but I can go anywhere from the sites in the left margin.
