While re-newing or activating the V1 2009 serial number, if you click to retrieve your registration key on the page that has the 5 empty fields and get a msg to check your internet connection, this is normally caused by a firewall. There are several types of firewall and can be software and hardware based. By default, Windows includes a firewall and most antivirus suites come with a firewall. Also, many routers include a hardware firewall.

The proper thing is to program the firewall to allow V1 to have the use of the internet, but in a pinch, if it is simply disabled, will also work.
