Anyway, make sure you don't have a firewall blocking toribash from connecting to the Internet. If you do disable it and allow access. Make sure it's from the accout administer.
Happened to me previously; now it should work when you download Toribash for your OS: http://www.toribash.com/downloads.php
edit1: I mean, try re-downloading Toribash...
