Hi @I_have_toes
Welcome to the community!
Sorry to here that you are not able to register your new account with an email previously used on an older account. Unfortunately, this email is attached to an old account and cannot be used to register for a new account. Do you have another email you can use to register for a new account? Alternatively, if you are the account holder and are able to pass account security on your older account, we might be able to see if we can transfer the log in information over. If you are able to pass account security on the older account, please join me on private message so we can go through this. You can see your private messages at the top of the page, in the envelope icon.
