Are you running Norton antivirus/firewall? I'd get rid of that and install something like AVG free or Avast! (for antivirus) and Zonealarm for firewall. They all have free versions.
Is that all the error says? Could be worth typing the exact wording of the error into Google. Someone will have had a similar problem before.

EDIT: just seen that you are using Norton… Try typing the exact error into Google before removing Norton.
