it is not working.
You log into the account using the email address associated with your account, not the display name (that seems to be the most common problem with people unable to log into the game).
Fate is just the weight of circumstances

We’d be happy to help, if you’re having difficulties. First, as Brother Grimm suggested, try using your e-mail address to log in. If that does not get you into the game, consider submitting a ticket to our Customer Support Team by visiting this page and then clicking the “Submit a request” option. Provide as much information as possible in the web form, because that will create a ticket within the support system. You are not required to provide all the information but may leave fields blank when you cannot accurately complete them. The team should be able to help you.
Best of luck, and welcome to Tyria!
