This is a public forum, not Adobe support. Users, including the ACPs and MVPs, are normal users as you are and can't provide support for account, subscription, billing, or other product activation issues. Support for those issues requires an Adobe employee.
Adobe provides support through the Chat function on the contact page or through a phone call. There is no email support.
CHAT: Click the following to contact Adobe customer support staff for help:
