Hi, I'm having the EXACT same problem suddenly as well. I've also used LW for about 2 years, never a problem, same computer, same modem, same antivirus and firewall but have been unable to connect for the past 3 days now. I uninstalled and reinstalled a few times with no success. I tried the fix that is mentioned in one of the previous threads but I don't think I'm doing it correctly and don't think I understand the instructions. Any help would be greatly appreciated!!!
Oh, I forgot to add that I am using Vista. Thanks
