Welcome to HBH! If you had an account on hellboundhacker.org you will need to reset your password using the Lost Password system before you will be able to login.
A app one question
When you move onto the harder app's you'll need Olly, it allows you decomile the application, and see how everything works….
Reason you didnt find the password for the APP is because you have to see how the application works in Olly. And with Olly it allows you to see more then what is viewable through notepad.
