No response received from Symantec server

I purchased NAV2009 from Best Buy.  Loaded on a laptop.  When i attempt to activate i get the message “No response received from Symantec server”.  I can access Symantec store but not customer support or activation pages.  i tried uninstalling and reinstalling.  i tried resetting IE defaults.  i am using wireless connection.  my LAN computer (this one) has NAV installed and works fine.  i took it to  my wife’s work and tried on their network.  Same result.  it must be malware or a setting on the laptop.  has anyone else gotten this message?
