Amazing to think the answer in the first post of this thread actually worked for me, and that was 4 years ago!! i couldn't connect to Limewire and had tried everything, opening the ports in my firewall etc.

Then to find out that all i had to do is delete the preferences directory is crazy lol the only thing different to the first post is that the 'limewire' folder is located here for me: C:\Documents and Settings\USERNAME\Application Data\

Anyway, thanks alot for that
