Thanx so much, now I am able to log in

I already created an account, how do I log out. Also if it matters I am on steam.

No, the only option there was to create a new account, I couldn't log in at all. And yes, this is the account in question.

Not sure where to put this, this is my first post, but I just installed the game (as opposed to the browser version), and I noticed it did not let me log into an existing account. Can someone help?
