You are talking of a lot of things that doesn't seem related.
Please go to
viewforum.php?f=3,
read all the red block of text, and describe your problem correctly, with logs and correct errors message.
"it's say I'm already in" is not a correct description.
First, what is "it"?
Second, when does it say that ?
Third, I'm pretty sure there is no "You are already in" message in the server, at all (so it's coming from your memory and it doesn't mean anything to me).
