weird, it should highlight the button blue (as you've clicked on it) then listen for a keyboard button. Once you've clicked the keyboard button, it should display that button under the bind key listing and under the start button. Just making sure, you're clicking the button, then pressing a key on your keyboard, then the program freezes?
