Apple Remote Control and Plex

Yesterday, I installed Plex to see if I would enjoy it as much as Front Row, which I use constantly. I haven't upgraded to Lion because I don't want to lose Front Row. Now, as a result, my Apple Remote control no longer works. I uninstalled Plex, but the remote still won't work. Any suggestions?

You might want to remove CleanMyMac. It has caused problems for many people by deleting files which ruined their OS.
