First of all, check you're internet connection. Cuz if that's not functioning, obviously no connection for you. Secondly... Here's (http://feral-heart.com/index.php?option=com_jfusion&Itemid=2&jfile=index.php&topic=10423.msg144690#msg144690) a thread by the Admin that covers "Unable to login/go online" issues (It wouldn't let meh quote it, so i provided the link instead). You might find a solution there.
