Test your internet connection to see if it works, that might be the problem

As Reyz said, check your internet.
Also try: Enabling Cobra. This will automatically enable Webman and will restart your system to do so
Whilst having Cobra enabled, make sure you have it on normal mode. (First option on that category if I remember correctly)

Enable Cobra in Rebug Toolbox!
