It wasn't just you. I was having the same problem around noon today. It didn't show any tourneys or ring games. After shutting it down and restarting it, it started showing games in the lists but wouldn't let me register for or join any. When I shut it down and restarted it again, it had gone back to not showing any games. I gave up after a few tries. When I came back a couple of hours later it was working fine.
