Thank you for your reply.
Finally I found the file myself in the directory you mentioned and installed it in CB. And indeed it transferred the language into Dutch.
Frits, I would like to ask you if you would help me to find the right settings for my inlog procedure. I have registered myself as a new member of the community.
But after inlogging I receive the message 404 - Component niet gevonden.
Perhaps its easyer to communicate about this subject outsite this forum.
I post this message also in oorzaak@oorzaak.nl
