Thanks for the support through email Ofer.
—FOR ANYONE ELSE—
I received a key from him and this allowed me to backup the files on one of his remote servers. To backup the translation files locally, you can backup the database tables:
wp_translations
wp_translations_log
*There are many good database plugins out there to backup your files.
**If your tables are still prefixed with wp_, you may want to look into changing them for security reasons.
