Lost key and unable to login

I accidentally removed the plugin, then installed it, the key is missing. When I try to login to the main site the email that is associated with the account is not one the I can read email from. I can’t add another account as the domain is already registered. I can’t ask for support because one has to log in to get support. I essentially either need my key (no email was sent the first time), reset my password ( I can’t do that because the email associated with the account is bad), or … not sure. I paid for this so this is very frustrating. a good email to use is [email protected]
