Did you configure your firewalls to allow LW full access: http://www.limewire.com/english/content/firewalls.shtml

From another thread I see you use XP. Do you have SP2? SP2 reduces simultaneous connections. There are patches but they don't always work. Many people have uninstalled SP2 & solved their issues. Unless you're running a large network & for business, SP2 is not really required, particularly for home users.

Might I suggest you try the new Beta which makes it easier to connect thru firewalls (but the firewalls still need to be configured.): http://www.limewire.com/english/content/beta.shtml Worth finding out if it fixes our woes!
