Well, here is an idea. I had these problems as well. Well, say I made an account. I didnt have time to activate it because I had to go to school. Well, when I get home, I cant activate my account BECAUSE: The registrations still have to be open if you want to activate it. So, say I made my account at 7:00 PM and the registrations close at 9:00 PM. Say I had to go to church or something for five hours. Well, after 9:00 PM, you can't activate your account because that is not the way the FH registrations are working right now. Do do what Kiquaii has said above about emailing activateferal-heart.com. They may give you a new registration link or something. If this doesn't help, it might come to where your friend needs to create a new account. Hope this helps!
