I read in a few other threads that to log in to the client, you have to put your e-mail address in instead of your username or whatever else. But my e-mail is, apparently, too long to fit in. So what exactly am I supposed to do to use the freakin' game?

I can't believe nobody replied to this. You login using your username, not your email add. It was only last time when Trickster was in Beta that you have to use your email add to login into Trickster through the game's website.

Why can't i login? I used my log in username and my PW but it said and error.
