1.Make sure your firewall is either off or configured to allow TB to connect.
2.Download the latest servers.txt here: http://www.toribash.com/servers.txt
Also, try hitting R in the server screen to refresh the servers.
doesn't continue to the next one even after a while ? that's strange.
I think it might be the firewall.
It allowed connections for the previous version of Toribash you used,
but some firewalls need to you open connections for new programs manually.
