in the header include information you have a include_once ("_app.inc"); but this file doesn't exist in your rar file. Maybe I'm doing something wrong but I don't think so.

Did you happen to download the Ladder Class. You will need those classes to make the tree view work. They are identified as Required Classes for TreeView.
