PRODUCT REGISTRATION

I recently purchased P6 Contractor, 6.1, with (I think) a successful installation on my laptop. I have access to the application, but my uncertainty comes from the difficulty I'm having in registering the product.

When I open the application, a registration panel appears. I filled in the requested info and hit "register" button.

This takes me to " oracle.com/application/primavera/index.html", "overview".

I have spent hours sifting through various sites linked to this page, trying to find a direct link to register the product, with no success. I'm surprised at the difficulty and lack of clarity in what should be a simple straightforward task. Am I missing something?
