I was playing and was kicked from the server with a 90000 error. Same as you, when I tried to start up again, the start button was grayed out. I waited, and was able to hit start, but then there was a lobby error, after passing that after another try, it said the NA server list couldn't be retrieved.
Guess I should go to bed now...
