I've used Limewire for a while now, but just lately it has started freezing up on me. I have previous downloads that would start connecting, but if I search for something, they all freeze. I would try to download something, and it would just be stuck on "queued". I have a strong connection, yet it seems to detect a firewall. Is the firewall causing all of this? And if so, how can I begin to download files again?
