You did not say whether you checked your spam folder and do it closely. Apparently some appear to be weird illegitimate shady emails, but they do have the code. Check again. People that received the first email (like me) in their inbox REGARDLESS of it being trusted or not was STILL sent to their spam folder. Try again and if you don't see anything after looking closely in your spam folder go to the forum post i gave

Additional: Yes I know you already registered a code that you received in your main email. This is different and may have gone to spam folder, read above.
