Request Username (isn't sending username to email)

Thread starter #1
Hello, I bought Mortal Online at release and was trying to find my old account but for the life of me I can't remember my username. But unfortunately the request username isn't sending me my username, I enter the information in correctly and it says, sending your username to my email, but after over a hour waiting it hasn't arrived and so I re-entered the email again and I have been waiting for around 45minutes but still no luck.

Edit: I'm using Gmail if that helps.

Going on day two now, still no luck. I tried to re-send it again, but still waiting.
