Software Not Detecting Internet Connection

I am trying to register my new Family Tree Maker Platinum 2008 software but it is not detecting the internet connection. I am able to get online fine but for some reason it keeps saying "unable to find internet connection. please try again later"when I go to register it. I tried disabling windows firewall and even uninstalled my norton software/firewall. Any suggestions??

 

i have a notebook that could connect and see my office LAN.But could not view any web page.the message is '' the connection was reset while the page is loading". the icon for network connection at the buttom right corner of the system occasionally shows 2 and two short bars across the icon.please what could be the solution?
