Ok.. so you still can't sign into msn messenger still? From what i've just read through you've set the clock to the correct date/time, firewall etc? If you're using the new MSN Windows Live Messenger then make sure your email account has been transfered to their new Windows Mail Beta service (from that green button in hotmail). are you connected to a router? If so: -Open up your router's config page, navigate to your WAN settings. -Locate something called MTU. If its set to 1500 change it to 1400 (little trick i've picked up) Windows firewall sucks. Get a proper firewall if you wish to keep your machine relatively clean.. Download Zonalarm Free or Kerio Personal Firewall.
