Maybe your installation went wrong. You should have a help file "Application Framework Help", "Database Deployment Toolkit Help" installed. They should also have installed as a shortcut on your desktop.
So what can I do to start trying your product?
I would surely like to build a solution that points either to your data or Northwind or AdventureWorks that demonstrates Customers - Orders - LineItems in my own test approach: List of all customers (searchable & filterable) with heirarchical grid of Orders with "child" Items.
