I bought the game, I installed it & created an account. I can log in on the website & forums, but when I log in on the launcher it keeps telling me that the username/password is invalid. Till now I can’t enter the game…

Addressing this common misunderstanding is on our “to do” list and we will be making a change that will make it more clear that the Account Name is the e-mail address and not the display name. It’s a surprisingly complicated change to make, but it’ll be made in the future!
