You may have given a different email address when resetting than when you registered. In order to be able to request a new password, the e-mail address provided must match that of your user account. If you are sure that you used the correct e-mail address, please check your spam folder. If you can't find the email there either, make sure your mailbox still has storage space. To free up memory, you can delete old e-mails. If all this doesn't help, you're probably not registered yet. In this case, please create a new user account to be able to log in.
