Can't fly my AR Drone autonomously using Libardrone Python

Question

I really need you help in this issue. I'm trying to use libardrone.py to fly my AR Drone autonomously. Here is my code:

import libardrone
from time import sleep

drone = libardrone.ARDrone()

drone.takeoff()
sleep(7)


drone.land()
sleep(3)
drone.halt() 

However, my drone will keep hovering after takeoff and it will never try to land. I got the following error: (I'm using windows 8)

Reloaded modules: arnetwork, libardrone, arvideo
Please install psyco for better video decoding performance.
Unable to bind video decoding methods with psyco. Proceeding anyways, but video decoding will be slow!
Exception in thread Thread-28:

    inputready, outputready, exceptready = select.select([self.drone.video_pipe, self.drone.nav_pipe], [], [], 1)
error: (10038, 'An operation was attempted on something that is not a socket')

is there any updated libardrone??
