Can you explain more? Did you buy the CD but need to download the program instead? Do you have a License Code?
There should be a card in the CD case that says how to download it and you will need the 14 digit code from it to enter.

But when it was done I clicked on Launch Now and the first thing the Activate box popped up and I did Ctrl+V to paste the code and it worked!
