You can not connect to the server unless it is online.
Which it has not been. I've had it down for a while, My internet has been messing up and the bill has got the best of me a couple of times.
It would be in you all's best interest to purchase one from the site if you like that type of thing. Being as how mine is rather unrealiable.
