We have had some challenges with resetting passwords. Your account has likely been imported but it must be "activated" first. You should now have an email with an account activation link.
If you haven't seen the email for account activation please check your spam folder. We have had multiple reports of the emails found in spam or junk folders.
If you'd like to simply create a new account you can do that here https://fenixnutrition.com/account/register
