Dear Ramonroldan,
welcome to IMSLP! I've seen that you've created a work page for the piano sonata but did no add the file properly. I've done it now. Please use always the link "Add a file to this work page" / "Añadir un archivo a esta página" and not the upload link at the left (sidebar). Regards, Hobbypianist 14:51, 25 April 2009 (EDT)
