Why can I not find a sign up button for Doll e 2?

When I click to go to Doll e 2 it sends me back to the original Doll e. I can’t seem to find any help. I did find a YouTube video that did a walkthrough, but the buttons he had on his screen were missing on mine. I also clicked a signup button in the forum here, but again it took me to my Doll E 1 account. Can anyone help?
