Hey oddy, If you want to get rid of limewire go to add/remove programs you will find it there. Make sure you get limewire from the official site as there are a lot of scammers out therehttp://www.limewire.com
Where did you get your limewire from? If it was from the official site check your firewall settings, go to the stickies in open discussion and check what you can do to get the best results from limewire...
