Can't Get To Front Row...

Help! I know my Remote is working because pushing play/pause will start/stop an iTunes song. But when I press Menu, it will not bring up Front Row. I checked my mouse/keyboard shortcuts as well, and it's set to bring up Front Row with Command + Escape. That is not working either. How can I check if it got accidentally un-installed or turned off somehow?? Two weeks ago I had to do an archive & install back to 10.4.4 (I believe), but would that have affected Front Row?

Please help! Thanks!!!
