Hi @jantrecec ,
You may no longer have access to the email address associated with your account. This happens sometimes when you change jobs and aren't using your work email anymore. This can also happen if you delete your email account.
For security reasons, we are not able to change the email address on your account (see below). Your best bet is to contact your former employer directly and ask if they can help you reclaim your Trello account by temporarily re-opening your old email account.
