Its dual session bug.

And i think u using acis "L2 Gold trance files".

to fix this bug open this file "net\sf\l2j\gameserver\LoginServerThread.java"

find this function "public void addGameServerLogin(String account, L2GameClient client)"

and change with this:

	public void addGameServerLogin(String account, L2GameClient client)
	{
		     L2GameClient savedClient = _accountsInGameServer.get(account);
        if (savedClient != null) {
           if (savedClient.isDetached()) {
               _log.info("Old Client was disconnected: Offline or OfflineMode --> Login Again [Account: " + account + "]");
                _accountsInGameServer.put(account, client);
            } else {
				_log.info("Old Client was online --> Close Old Client Connection [Account: " + account + "]");
                savedClient.closeNow();
               _accountsInGameServer.remove(account);
            }
        } else {
            _log.info("Client was not online --> New Client Connection [Account: " + account + "]");
_accountsInGameServer.put(account, client);
       }
	}
