Change Language using NavCoder
 

I am having some troubles changing my Nav and System language using NavCoder.

To be able to change my Nav from english and French to English and Dutch I downloaded the V32 OS from Neiloakley (not the modded one)

First I started NavCoder, pressed Read Language.
Then I changed French to Ducht, and pressed Code Language.

My system ask then for OS CD which I insterted and system starts to upgrade.
But unfortunately no changes are made to the language.

Can someone please advise if do need a different OS CD. Because I just can seem to make it work.
