# spanish option for babel

I recently updated my Miktex 2.9 and when I try to compile my files I get the following error, which I didn't have...

package babel error: unknown option spanish. Either you misspelled it or the language definition file spanish.ldf was not found.

This is my preamble:

\documentclass[12pt]{article}
\usepackage[explicit]{titlesec}
\usepackage[usenames,dvipsnames]{pstricks}

Please help us to help you and add a minimal working example (MWE) that illustrates your problem. It will be much easier for us to reproduce your situation and find out what the issue is when we see compilable code, starting with \documentclass{...} and ending with \end{document}. – user31729 Jun 11 '14 at 6:01
The organization of babel has changed. The languages has been separated into separate distribution packages and are now independently maintained. In MiKTeX you have to install babel-spanish to get babel's spanish.
