This is the same issue Im having to and I was going to start to play this pserver today. Also I found out why this is happening is because we skipped the account vertification which we need to be able to play . Go here and verify your account http://royals.ms/forum/showthread.php?t=672
Yes there are clear instructions on the page that appears after you register your game account. I am assuming that a lot of people seem to not read this.
Yo Matt, I followed the instructions and completed what we were supposed to do in order to play. Would you mind reading mine so I can play now? Been waiting two hours to play.
