Ning To BuddyPress csv export link dead?

Currently I'm translating the Ning To BuddyPress from
https://premium.wpmudev.org/translate/projects/nbi/

I tried, but the following link is not working.

Source: "Please export your Ning network members to a CSV file and upload that file here. If your CSV is too large, you can ftp it to the "%s" directory and rename it to "ning-export.csv"."
Reference: /Users/aaron2/Documents/WPMU-Test/wp-content/plugins/ning-buddypress-importer/includes/ning-buddypress-importer.php:606

Could someone please provide the correct link and change the source?

Thanks!
