I tested a new registration of a prosite. There is supposed to be a Welcome message immediately after a new registration, enabling the new user to go through the Paypal checkout. After testing, it went to a site that said "could not be found." This was the URL the process directed to: http://wordsandwriters.com/pro-site/?bid=365. It did create the site (through the New Blog Templates plugin).
Thanks for your help. Access has been granted if you want to take a look.
