Hello Everyone, Since the recent update of my itunes (to 4.1) I get an error message saying that port 3689 is being blocked by my software firewall, so users can't access my shared music. The funny this is my software firewall (Norton Personal Firewall) is deactivated and has been deactivated for some time. This has never happened before. What's going on and how can I fix it? Thanks for your time.
