I , too, am having trouble with Limewire connecting. It shows it indicates a firewall even after I have shut the firewall down (Windows) and fully closed Limewire and reopened it. I have Windows XP with Cable modem (Roadrunner). I have more than ample memory. Usually I can close it down and go back into it and it's fine but lately it just doesn't want to work. I recently downloaded the most recent version of Limewire too. Any ideas?
