If you bought Diamond with a different email address, the license is attached to that one — sign in with it instead.

This erases your email address, your password and every machine fingerprint we hold, and signs you out everywhere. It cannot be undone.

Your payment records are kept — bookkeeping law requires it, and that obligation overrides erasure. Your license is not canceled: you paid for it and it stays valid. But without an account you will not be able to look up your license key or free a machine slot again, so save your key somewhere first.
