Self-voicing is enabled. Press ‘v’ to disable.
That is not an error message. It just informs game is reading aloud text on screen. Sound may be muted, so it is useful to know this voice thing is on.
Are you saying it does not turn off when you press v-key again?
The other pop-up is an error, although I do not understand spanish. Does sound work on that computer?
If you download a new copy of the game it may use the same persistent data, so same fault keeps appearing.
I found from https://www.renpy.org/wiki/renpy/doc/FAQ that
The Ren’Py engine stores save games and persistent data under a separate folder. It’s exact location depends on the host operating system. Windows: %APPDATA%/RenPy/game_directory This is usually: C:\Documents and Settings\YOURNAME\ApplicationData\RenPy\game_directory Where YOURNAME is your username.
My guess is some file in that directory stores the state of having pressed v or some other key you pressed that caused this fault state. Maybe if you keep the save files removing all the rest, and then install new copy and restore the save files?
