Table : piwik_user_language' doesn't exist

I’ve updated my Piwik from a very old version to 0.4.2 and after updating the date base I had this message :
SQLSTATE[42S02]: Base table or view not found: 1146 Table ‘xxxxx.piwik_user_language’ doesn’t exist.
I can manually create this table, but I don’t know what to put in it…

Any suggestion?

Go into Settings | Plugins. Deactivate and then reactivate the LanguagesManager plugin.

Thank you !
I’ve done it !
