but the ConfirmActivation page does not come up that supposed to display a successful message.
Seems the code is not complete, the create new user event should be in your CreateUserWizard1_CreatingUser event, redirect to ConfirmActivation page should be managed in this event.
Please provide more back end code so that this issue can be reproduced and fixed.
In addition, please also check Creating User Accounts (C#)
for detailed tutorial.
