Even if the email account is not a working email address for you, at this point it is only a login name for that Roku account. As long as you know the password you set up when you created the account, you can still log into it at https://my.roku.com by using that email address. Once logged in, you can:
To then connect your Roku to the correct account, do a Factory Reset via Settings > System > Advanced system settings > Factory reset. You'll then be setting the Roku up all over again from scratch, including linking it to your desired existing Roku account if you have one, or create a new one.
- If this is a pre-existing account, channels already on this account should install.
- You may need to log back into all or some channels that require logins.
- Any subscriptions you had through Roku on that other account will not transfer. If you still want them you'll need to resubscribe.
