I was able to use your files and when I test it I get the full set of advanced file management. The only thing that I needed to do was to load the db that I had in place for my live version.
When I loaded this db locally I was able to use your files to get at the advanced file management features. You should try doing this on your local testing server, load the db that you have from the live server that includes all of the kfm_ prefixed tables. If you have any more trouble with this let me know and I can open a ticket for you.
