Adobe ID authorization not working

Good evening Adobe!

I bought a new ebook and wanted to move some of my books from books.google.com to it using Adobe Digital Editions.

The problem is that it does not let me authorize my computer although I tried with Google option with my google account. Also I tried creating this account which I'm using to post this discussion... with Adobe ID option selected and my email and Adobe ID password, and it does not work either.

Then, I tried to visit this link displayed from the application http://www.adobe.com/es/products/digital-editions/ebookcreateid.html but it shows me a 404 page not found on my browser.

Could you please help?

Regards!

Juan
