[Wrench]

I don't really know the correct line of this, it says that my name isn't correct, Select a name between A-Z and 0-9... Even my name is Wrench there...

-Check of you did not put a spacebar behind your nickname.
-If you did not put a spacebar behind your name, try relogging at least three times.
-If you keep getting kicked, try relogging with another name to see of that works.
-If this doesn't work either, report the issue to the server developers from that server.
-If it is your own server, go to the scripting help section an ask for help there.
