Hahaha!Maybe the site is down, or maybe it isn't up for the day. Don't know if it matters that you are in the UK. I had to wait several hours to book for our trip last year because there was trouble with the site. What did you decide to list for your ADRs---maybe I can distract you for a bit.
We ate at the counter service at England and it was excellent. So if you get a chance, stop by there and check them out.
