Guild Wars 2

I have always had my launcher memorize my password, so I don’t have to type it in. but for some reason today when i opened the launcher, the spot for my password was blank, and a few weeks ago i changed my password, and now I can’t remember it.
I clicked on the “Forgot your password?” link and got a page that just says “Not Available”. I then went to the GW2 site and was able to log in to that, since it had my password memorized. I then logged out, and clicked on the “Forgot your password?” link from there, and it took me to the password recovery page. However, you need your serial code to recover your password, and I no longer have the email containing that code. How can I recover this?

If you bought it directly from ArenaNet, you probably can contact the support and they MIGHT be able to help you. If you got it through other vendors, try contacting them and see if they can help you out.
