Barbara -- Something similar happened to me. I couldn't get the page to load from my desktop computer, but tried on my laptop and it took awhile, but finally loaded. I couldn't get the state part to work. It didn't show any state options and when I clicked on it, nothing. I decided to try to register without that and it kept telling me that I didn't enter a t-shirt size. I was afraid to refresh for fear of not being able to reload the webpage. I kept trying and trying, then finally my desktop got a webpage, I registered there and got #161.
I've heard that everyone will move up due to the server crashing and multiple registrations, but I'm not sure if it will go out as far as my number. Hope it does though and will for you, too!
