I had the same issue yesterday on both computers, one at home and one at work. I'd be logged in when I hit the Home area, but if I hit the large F6B Riders at the top, it would be empty in the upper right hand corner and I could not go anywhere on the site and told me I had to log in or register. Finally after 20 damn attempts, it went to the LOG IN page, I put in my name and password, told the computer to remember it, and all ended up fine. Go figure!
