Cannot Apply new Subscription Key to NIS 2009

Hi Folks

I attempted to renew my subscription of NIS 2009 but the Austrailan portal kept rejecting my credit card details by say it could not verify my details. so in desperation I renew my subscription through the US portal and was sucessful and received the Subscription Key/Renewal Code. However when I attempt to enter the new code I get an reeor message say it is an invalid code. I have even resorted to uninstalling NIS 2009 and then reinstalling it to no avail. on reinstallation the installation keeps using the old product key.

I need advise on how I can apply the renewal code I paid for or who I should contact to get a vail code

 

Thanks in advance
