Log In Alone

I want to read my manga but it won't let me log in. What's happening? I already downloaded the new update but I can't log in anymore. What's the point of posting a comment if they don't respond?

Translation feedback 1:

- Main menu display "REGISTRARSE". I don't what it says in English. Then in the register/log in page, it says "Registrarse" twice. If this page is meant to log in, in the main menu should say "INGRESAR" (Log in) and in the log in page, the button should also say "Ingresar".

- Settings menu displays the option "feedback", translated to "retroalimentación". That's a literal translation and does not fit. Instead, you should replace it for "Danos tu opinión" (Give us your opinion).
