Aye, that tends to happen after each patch too. They did a server restart to help this. To quote from the FAQs in the forums:

Question: Why do I lag badly after a server restart? Why can I not login and get stuck at 'Verifying Account'? Why after trying to verify my account, does the game drop my login connection with the error 'Disconnected'?

Answer: This is due to the server restart being run, usually just minutes after you start getting stuck on login. This is caused by everyone trying to login at once, causing some people not able to login at all, while allowing others to login after sitting at 'Verifying Account...' for a good few minutes, but lagging horribly during gameplay. Sometimes users even get disconnected and get handed a 'Disconnected..' message after trying to verify the user's account. This usually smooths itself out after 45 minutes to an hour of the server being restarted. Give it some patience and keep trying.
