You all got something, i just payed today via paypal 19,99 dollars, but no link, no download, no registration e-mail, nothing!! Tomorrow i will ask paypal for refunding my money.
If your paypal email is not the same as your Stardock login email then all you need to do if transfer the registrations to your Stardock login account.
You can do that here - http://www.stardock.com/support/registrations/ as Wizard said above.
Put your Paypal email in the Source account and your Stardock login email in the Destination account.
