How to stop Flash Media Live Encoder on Mac OSX version 10.8.4

I can't stop Live Encoder 3.2 on my Mac. I re-downloaded it twice from Adobe. I checked for updates(none available). The Encoder works great while I am using it. But, when I try to stop it, my system freezes up everytime. I have to unplug to even shut-down and restart. Can anyone help?

This is the code I used for my settings...
