Could Not Connect To Host

I have searched and searched for this topic and can't seem to find an answer. I updated to version 2.58 and am now getting an error when I try and use any of the selections under Tag Sources. The specific message I am getting is:

Mp3tag program is not being blocked by my Norton firewall. Any suggestions as to what it might be?

How do you know?
Anyway: please check MP3tag's web access with the function Help>Check for updates.
If you get the information that there is no newer version then MP3tag has web access.
If you do not get any response then MP3tag does not have web access and consequently also no script has.
