(SOLUCIONADO)problema al instalar idioma

[nemodigital]

Es la 4ª vez que instalo prestashop y no suelo tener problemas, pero estoy volviendo a instalarlo y no se por que me da este error, por favor decirme algo, me estoy volviendo loco.
Lo instalo desde el instalador, lo instalo desde el ftp descomprimido, ya no se que hacer.
Y el error es este:

This language is NOT complete and cannot be used in the Front or Back Office because some files are missing.

BUenas noche,

Por mi parte he descargado el instalador de prestashop en la pagina oficial.
Le he decomprimido y transferido por ftp.
Todo ha funcionado bien, pero viene con los pack de idiomas francés y inglés.
Despues he descargado el pack de idioma español en la pagina web.
En el panel de control "Outils>langues>nouveau " añadir español con las imagenes
despues en "Outils>traduccions>importer pack de langues" el de español.
Despues todo listo a parte que falta muchas traducciones.
Que te vaya bien.
Un saludo

POR FIN, he solucionado el tema de la instalación. Todo era por que en añadir idioma, en el campo ISO yo ponía SP en vez de ES.
Menuda tontería y la guerra que ha dado.
