How to retrieve a password using my email address to recover my account?

Hello everyone, I am reaching out to you all in order to resolve this issue I am having. So I was finally able to download the game but my main issue I am having is how to get a registered ID in order to fully access the game? I was able to get an account setup to communicate with everyone in the forums but as far as getting a registered account that seems to be difficult.

To be specific when I am at the homepage, I'll click on the "REGISTER" tab and then a prompt will pop up that will require me to fill in my basic information such as my first name, last name and my email address. After finishing up my information I noticed I didn't receive a prompt that will require me to validate my email address so I just went on to start the game. I tried to access the game but my user ID is not registered. I tried to register an account again using the same information but now I am getting another prompt saying that my username or my email address is already used. So I am saying to myself if that's the case then is there a tab where I can use my email address to recover a forgotten password? At the end of all this, I was wondering if there is a section in the website where I can recover a lost account because that's my biggest challenge that I am having on this website as far as navigation goes, everything else is good to me. Sorry for the long issue but I just want to be specific.
