Because the subscription is tied to your existing email account, the admin cannot be replaced while the service is active.
If you are enrolled in the monthly Remote Admin you will need to go to your subscriptions page and cancel the service. Once the subscription expires, then you'd be able to replace the admin account. If you cannot wait until the subscription expires, please visit the following page to create a subscription case and we will be able to cancel the service for you earlier (just be aware that we cannot issue a prorated refund for the early termination):
