Its soviet, last night i was playing on the Minigames server till 1 oclock. and it was working perfectly fine. this morning, at 9 A.M. i tired to join and 4 1/2 seconds later after i joined a team, it kicks me and gives me the message, please disable any plugins you are running.

WTF? As, far as i know, i m not running any plugins, I dont have any custom skins and i am clueless about what to do. Help>?
