How to find the Paypal checkout after registration

I have some users who registered for a site, filled out the form for the username, password, etc. and clicked on "Reserve My Site. " Then, they went to the Paypal checkout, but did not complete the process and then got kicked out of the checkout process.

So now they are in limbo with registration done, but no checkout complete, thus no activated site. When I go to my Super Admin area, the site does not show up.

In the previous version of Prosites, the site showed up and I was able to find the URL to send to the user to complete the checkout process.

My question: how does this user complete the Paypal checkout? In the past, they could go to usersite.wordsandwriters.com/wp-admin and they would be redirected to the checkout. How do I get them to the checkout page now?

Thanks, Joe.
