When I get to the Secure Server, it asks me to login with a Customer ID and password. I don't think I have a password. You don't need to login at this stage. The Customer ID is for Registered TitleSearch Customers, who have their invoice and delivery address details stored on the server.
Some people are able to login without any trouble after making a purchase, others end up stuck.
