Your practitioner set up this registration page so that it only allows you to register using a specific email address, so that we can link that address up to your existing data. If you're seeing this error message it means you're not using the email address selected by your practitioner. Here are a few things you can try:
• Are you registering with the same email address that the practitioner sent this link to or another address? Try using the address you received this email at.
• Are you registering with a personal email address? Try your work email address.
• Did you type your address in correctly?
If none of these help, reach out to whoever sent you this registration link for more details, or contact our support team by submitting a ticket at https://herrmann.zendesk.com/hc/en-us/requests/new or sending an email to firstname.lastname@example.org .
