How to update an allready existing translation:

* Save the old translation wherever You like
 (*not* .../kflog2/po/<your_language>.po)

* Open the menuitem Settings / Configure Dictionary / PO-auxiliary
 and enter the path to the previous saved file.

* Copy kflog.pot to <your_language>.po and open this file in KBabel.

* Select Tools / Rough translation.

* In this dialog, add the PO-auxiliary to the used translation
 databases.

* Press Start and relax :-)

After that, KBabel tries to translate everything by using the old 
translation.
