Windows Live Messenger Error Code 80072745

I have also just downloaded the new Windows Live Messenger and when I try to
sign in to it i get the following message window,

"We can't sign you in to Windows Live Messenger. There might be a problem
with your internet connection. Make sure your computer is connected to the
internet.
Windows Live Messenger has made severaal failed attempts to sign you in.
Your firewall may be blocking Windows Live Messenger from connecting to the
service. Please review your firewall settings See the retailer's instructions
for more information. Erroro Code 80072745."
Error 80EF01F7, 80072745, or 80072746: Service is not available

This feature is not available in some markets.
I have done all the troubleshooting recommendetions to no avail.

Why email me with the upgrade to the 2009 WLM when I can't have it??????
