Can't login/register at wowhead.comFollow

Hey guys,
I can't login at wowhead.com with my ZAM login data. (at lolking.net does it works without problems) I tried to register at wowhead.com with my email and it says, that they will send me an email with further instructions, but I never received that email. (I also checked my spam folder!) I tried to register with 3 different email adresses at wowhead, but it does not work at all. I hope you guys can help me.
