Have been using Limewire Pro with no problems for months. All of a sudden I can't connect. All I can do is to click on the icon and then I get the message saying 'Loading User Interface'......and that's it! Can't get any further? I have tried shutting Win Firewall.....no luck. I use Norton Anti-virus, would that have anything to do with it? Although I have not made any changes to anything, it just isn't working. Any P2P gurrus who can help me out?
