Hi FearOfGod,
Sorry for the inconvenience caused here. Could you tell me which e-mail providers you and your friend are using? After testing our registration e-mail on different providers, we found that Yahoo, Hotmail/ Outlook and Gmail worked the best. Also, did you try checking your spam/ junk folders, in case it ended up there?
See here if you're still having issues.
