As a quick workaround:
Open SYS:Prefs/Internet, select "Hosts" on the left side, click on "New...". In the new window enter 207.200.98.25 as IP address and classic.shoutcast.com as Host name, then click "Use". Save and make a reset.
And don't forget to remove this when TN gets a update to fix that.
And its still working here, Just hope Bean will update Tunenet soon and fix this.
