Try the NOT EXISTS operator:

SELECT Customer.CustomerID AS CustID, Firstname, Lastname, Username,
Password, Question, Answer, Email, Age, Gender, Address, City, State,
Zip
FROM   Customer
WHERE  Customer.CustomerID
       NOT EXISTS (SELECT *
                   FROM   Registration
                   WHERE  Registration.CustomerID = Customer.CustomerID);
