Sorry, my english isn´t very well.
The ScholarPress Courseware Dutch translation is done, you have it in:
wp-content\buddypress-courseware\languages\bpsp-de_DE.mo & bpsp-de_DE.po
to change courseware language, you must do this things:
1.Copy bpsp-de_DE.mo & bpsp-de_DE.po to the "i18n" directory ("i18n" is in the same level of "languages" directory).
2.Delete all files from "wp-content\buddypress-courseware\languages\" except "bpsp.pot".
3.You have to change courseware.php file ("wp-content\buddypress-courseware\") in the same way that explains in this link:
In resume, the modifications are:
-> Delete "'/languages/'".
-> Include "'/i18n'" (this is the new path to dutch version).
4.You must have wordpress in dutch, but it isn´t enough that wordpress options and dashboard appear in dutch. The option that you have selected in (WordPress dashboard) Setting > General > Site Language > MUST BE DUTCH.
