I'm running Limewire PRO 4.12.6. I have my normal Windows Firewall on, and I have it set to allow Limewire, yet the firewall is still blocking it. Limewire was working just fine before I had to leave for work at about 5 PM today, my bars showing the connection status were light blue; but when I came back and got on at around 9, the firewall blocked it when I started up Limewire. What's going on and how I can I fix/prevent this?

Thanks,
Phil
