i try to login but it says Account or password error. Did i do somthing wrong? Is the login server down? Did i do something wrong? I'm pretty sure i put in the correct information, i tried at least ten times...
First, make sure that you've selected the correct set of game servers. Start the game launcher, then click Region/Language. Select USA and English from the drop downs, then click Apply.
Secondly, passwords are case-sensitive. Make sure your Caps Lock isn't on.
Either/both of these usually fix the issue.
