I just manually over-rode McAfee Firewall and shut it down completely. I was then able to connect, search and download a file without a problem. I've had McAfee Firewall running for the last several months but it's just been the last week or two when I haven't been able to connect to Limewire. I guess I'll continue trying to connect with the Firewall up and running, and if that fails, I'll turn it off again and try connecting that way. Hope this helps some of you.
