Windows Live Messenger Nt Working over the Wi Fi

My BIS Subscription expired .. so i decided to use my WLM over the Wi-Fi But there is an error always appearing which says : "Connection Error (65) : Problem receiving data from the server "
So What can I do to sign in ? or i must activate my BIS subscription ??
Thanks :)

Its not supposed to, only over BIS or BES. Use a site like m.ebuddy.com to login, or use an app like IM+ or Trillian.
