Importing Language module in nav5.0

Hi All,

I am using navision 5.0. I need to import french language for one of my clients. I just downloaded navision language module and installed in the installation folder of the cside / client itself. Then I import the .flm file everything goes fine. But when I select the french language in the application language window the cside gets closed and a run time error is thrown.

The error msg is:- R6025 - pure virtual function call

Can any one provide me the solution to import french language.
