Great, plz send the files to ssl(at)gmx(dot)de.
You have to copy these files into
administrator/components/com_uddeim/language/
administrator/components/com_uddeim/language.utf8/
so uddeIM can find them.
Note that uddeIM uses the same filename as Joomla uses for its language file. So when your Joomla language file is "slovak.php", uddeIM also looks for "slovak.php" in the folders mentioned above.
