Often the case with using Norton & updating it is you need to remove the previous 'exception rule' and re-add it, so remove BearShare & re-add it as an exception for Norton. Only run one firewall. So choose between Norton & XP's firewall. The reason for this is Norton & XP's firewall clash, & cause problems including less security. Have BS as exception on whichever firewall you choose to enable.

Also make sure each Bearshare on your home network is using different connection ports.
If still problems, check
