Guild Wars 2

Because I was having trouble logging in to my account after uninstalling guildwars a few months back, I decided to change the password and download again. (I quit playing for different reasons…) Anyways, after changing my password, I opened guildwars up and it says, “the account or password you entered is invalid.” Obviously after during some confirmation through email I am able to use my account on this website however when I open guildwars itself, my new password doesn’t work and it just references me back to here. Can somebody help me?

Hi!
