You have to rename the documentname also, it has to be bbpress-nl_NL.mo
What language is set in your WordPress installation (your dashboard, is is in english or dutch?)

If it is dutch it should work immidiatly, otherwise you have to make a small change in your wp-config file.

Change this line in wp congif:

define ('WPLANG', '');

to:

define (‘WPLANG’, ‘nl_NL’);
