norton internet security

For the Fourth day now, I have been trying to download the norton internet security I purchased for another computer that I no longer have in my home.  I have the receipt, all the numbers I need, have done everything I have been told in the e-mails from customer support, yet no luck.  This mornings offering was to open the product and above the cyber-crime heading on the main page click on activate-renew. and of course, there is nothing like that there on the main page.  I have searched where I can get to on the website, and can find no where that I can put in my product number to get this straightened out on the new computer that I have.  Can someone PLEASE help me!
