Not working for me

This thing connects to the server, displays what looks like a unix directory listing and then sits there.
If I drag a file to the window, it will upload the file, but that seems to be all that is working.
It does not do anything else as far as I can tell. The UI will highlight a row if you click on it, but that’s about all.
Dragging items for download is NOT working and I can’t navagate directories.
Maybe its just not compatible with Mavericks, or maybe it never worked in the first place.

The support link is usless.
