LOTR,
I have the same problems. we just moved recently and now my limewire will not work. I deleted the .limewire directory, disabled my firewall (windows XP), looked at my ISP, cox communications website and saw that port 6346 was not blocked or filtered, went to my router at portforward.com (dlink 614) and allowed port 6346 viva both TCP and UDP and still no connection. Any help will be great. Thanks LOTR
