I am assuming you are using a hd install, there are several ways to fix the language problem, look here:http://www.knoppix.net/forum/viewtop...highlight=i18n to set the language globally for the entire system. You'll need to log in as root and edit the file, then reboot, and you will have english as your default language, then you will have to follow the FAQ on the CD or Knopper.net for converting KDE from german to english.

Or you could just delete your ~knoppix/.kde directory and then you'll get the first time KDE setup wizzard when you log in. If you just change KDE, it will be fixed but some console based apps may still be in german, if you fix the environment settings and kde the whole system will be in english.
