Are you sure, you are connected to the internet (unless of course you are using the same computer to post this question)? – Ankit Feb 12 '13 at 17:21

Same kind of problem I faced few days before. I figured it out there was some network changes. Make sure that the method use to connect with network will be selected as "none". You can get this option in network proxy interface in network settings.
