Hi,
I was forwarded a bring a friend beta key email, with the "additional beta key" in it, and I used it and it worked. However, the friend who sent me the email cannot find his own beta key? He just created his account today and the only key that he can find is the one that was sent to me, which is now invalid. He had signed up for beta back about a year ago, but before Feb 27th 2014 he has no emails from ESO.
Any help?
