An error may occur during registration or login. This can have various causes.
If registration does not work, the most common reason is that you already have a user account with your email address. In this case, you can simply log in: Login
If login does not work, the combination of email address and password is usually incorrect. In this case, you can create a new password using the Forgot password function. An email will then be sent to you. If you cannot find the email in your inbox, please check your spam folder.
If the problem persists, please contact us using the contact form (German or English only).
