We do not have access to accounts/billing/licencing here, this is a user forum.
You will need to contact support for licencing and account issues.
You can raise a support ticket by using the form here: CCleaner Support Community
However you should note that support are slow to answer these days and it can take a week or more for a registered customer to get a reply.
