If i look In your English file can i found:
$hesklang['err_dbversion']='Too old MySQL version:'; // %s will be replaced with MySQL version
but %s is not there, but if i look to Italian (Italiano) language file is there: $hesklang['err_dbversion']='Versione %s MySQL troppo antica:'; // %s will be replaced with MySQL version
and here i located my problem, if i delete %s from the string and update my page is my swedish language file in the list and my swedish language file worked without any problem.
