After completing a registration, you'll have to set in-game password: Visit a profile preferences page and find the "In-game Password" field (or click here) Enter an in-game password (you may even enter any random symbols, you'll not use it for logging into the game) Press the 'Save Changes' button at the end of the page If you're registered, visit the main forum page; if you're not, then complete a registration. Complete the 1st step again You'll get an automatically generated password that you'll have to use to log into the game. Repeat these actions if you want to change your password.
I was having the same problem even after changing my generated password but solved as you have to put your USERNAME instead of E-mail address in USERNAME field
