having the brick wall symbol but that should not matter as long as Limewire has permission to go through that Firewall. My Vista says it has detected a firewall but Limewire has automatically set itself to be allowed through the firewall. This should havd happened automatically on your version during Limewire install too. if you are still being blocked by the firewall you can go into the settings for the firewall through the control panel and set the firewall to allow Limewire access to the web.
