Oh my gosh. I figured out the problem. Apparently despite hitting, I thought, every key on the keyboard I never tried E? I don't know if that's the other person's issue but maybe, in future, you could had a note of some sort on the first dialogue to say you advance text with E in case some people don't look at the controls (which I am imagining are in the settings but, quite obviously, I never looked).
Thanks for the speedy reply.
(As a side note, there is a typo or miss-translation in the menu when you hit escape within the game it says 'General Volumen' instead of just 'General Volume'.)
