Hi, 

I tried to log in with the wrong account and now I cannot get it to reset so that I can log in with the correct account.  Please tell me how I can get back to the original log in screen so that I can put in the correct account.  I don't want to lose all of my progress.  Thanks!

on the main screen where you tap to connect to whatever server, look in the top right corner of the screen there should be a log out button.
