this is the inventory bug, there is lots of info about it via the forums and chat box. if you've already logged in while your character is naked then all of your equips are gone. if any of those equips came from your own personal donation then speak to Dex via chatbox or PM Admin on the forums and see if he will reimburse the donation package.
otherwise just get new eq, because your old stuff is gone next time, if there is a next time...do not log in. just alt+f4 the game and then teleport your character with the user tools. log back in, see if its still naked....rinse/repeat
