I'm sorry, I don't really understand :(
Okay, I had the same problem. What you wanna do is log out from the account you created to go back to your original save. Your progress should still be there unless you deleted your browser cache and cookies(assuming you played the browser version).
After that, press play to go to the home screen, then press account. Under your character's pfp, there should be a black box with text. Click that to get your userID. Then hop back over here and login with your user ID.
