It's not doing anything. It was installed, opened but the volume buttons still control comp volume. What am I doing wrong?

Matt, do you see the app's icon in the upper right corner? It looks like this: http://i.imgur.com/ZWhHdeJ.png
If you see that, and its color is black (instead of gray), the app is running and enabled.
iTunes also needs to be running.
If you're still having issues, could you send me the version of OSX and iTunes you are running? Thanks.
