When you say no language change, do you mean the language is not available or there is no translations shown. I.e. does the language show up in the language selector?

After adding the language itself, there are some sql files in your install/database directory related to translations for each language. You will need to import these into your database. I suggest phpMyAdmin to do this or to copy the one you want to var/database/backup directory and then “restore” it via the Administration/database restore functionality.
