Download link for guests

I have a really big problem, i just finished a web where guestS can checkout without registration, and that is awesome. But when they receive the email of the confirmed payment, the download link take them to the site, where is a login, so, is useless.

Please help me! Thank you

The url is:

agapobuendia.com/

I made a user for this issue:

user: hikashop
password: hikashop

I did a temporal solution, but is not right.

I made the link download free, and in the css, i hide the download link on the product page. That way, guest that already paid, can download the content directly.

Of course, this is not the right way, but it works for now.

Thank you in advance.

Sue.
