How do you make it stop?

How do you close this program??? I know it gave me a pop up when it opened saying what keys you have to push to open the toolbar... but no where on that pop up did it say "warning: not reading this means you will spend a rediculous amout of time being frustrated and trying to close this aweful program" As soon as I figure out how to stop this program I am DELETING it!
