Hi Mike,
First, it was the link on/after the 'Thank You for submittal" screen
Second: in phpESP.ini.php line 92 Rdemark for en_US and a line for de_DE
// Default language for designer interface
// (Must have gettext support avaiable.)
//$ESPCONFIG['default_lang'] = 'en_US';
$ESPCONFIG['default_lang'] = 'de_DE';
