was the error the same on stu's computer? have you tried to disable Mcfee and try it? does your Mcfee have a firewall or just antivirus? does the socket error stay the same or does it ever change to something else? are you running peerblock?
my guess is that at stu's y'all just didn't wait long enough for the torrent to show up and on your computer Mcfee is blocking things.
