Answer 1

I think that you must set the boolean stop to true at the end of your catch.
That would fit the immediate error, but as i do have have the whole source i cannot say.
From what i see this will not solve the problem, should the user cause the error again.
By the way, is this the same problem as the other post with the broken if statement?
Your new catch statement will look like this
catch (NumberFormatException e)
           JOptionPane.showMessageDialog(null, "You must enter a number format for Membershp Number");
           this.dispose();
           new PersonalDetailsScreen().setVisible(true);
           stop = true;
}
