Are you getting a message when you try to login to your xOffice account that you need to register?
To register for the xOffice, go to https://xoffice.ariix.com/XOffice/ and click on 'Register for ARIIX xOffice.'
Next, enter your ARIIX ID number, click 'Continue' and then follow the prompts to complete your registration.
When you're all done you'll have set up your password and you'll now be able to start logging into your xOffice account!
(If you enter your ID number and you receive a message stating that you have already registered for an xOffice account, you probably just need to reset your password. You can do this by clicking on 'Forgot Your Password' and following the prompts.)
