The "Queue" is just an error message that generates a random number after the "Average wait time:xx." A queue does not actually exist. It is the reason why they don't answer the "do i click ok or not": questions on the forum. What is happening is that no one could get on yet again because everyone tried at once and they have no queue. They lowered the max population to like 100 people, once that fills up, then they increase it to 200, 300, etc. Ignore the message box and keep trying. They are banking on the fact that people will leave the error box up and think they are in an actual queue.
