How do you generate the unique 6 digit hardware ID? That's a major problem solver.

The form is modal so the user cant do anything except press ok or register. If Ok is pressed the user can access everything normally. After the limitation expires the ok button is no longer available, so the user must exit or register.

This file's creation and access dates are always changed so that it cant be easily found. The application will close down if left open for a period of time, thus requiring another launch.
