Trouble finding downloading url after buying a product with files.

Hello -

Im trying the plugin using Sandbox. After I complete the sale with a "sandbox email" buying account from paypal, it says the order was successful.

The tracking page says the following:

And then, the manage order page says the following:

Your payment for this order is not yet complete. Here is the latest status:

The payment is pending because it was made to an email address that is not yet registered or confirmed.

Im not able to determine why cannot I see th download links. The paypal sandbox emails cannot be registered on the site, besides, what if someone chooses not to register and simply buy a product... I even changed the status of many orders manually to "paid" - still no link...
