I got the same issue, I reinstalled the game after some time. I can log in here but i can not log in on the game client. And yes I can type my password, which should be obvious or else I could not write on this forumthread, and I tried both, my E-mail and my Account-name on the Client. I even tried one of my old character’s names.
However none of the above works for me and I keep getting the same Error code.
