My Automator is broken?

When I go into Automator, under my actions Library, all I have is three options: Fonts, MAil, and Music, and each only has one suboption. Any idea why this might be happening?

Is there any way to “reinstall” Automator without completely reinstalling OS X?

Create a new user account in OS X. Log into the new user account, and see if Automator works there.

If it does, you have the same problem I had. To solve the problem, you simply need to trash Automator caches and preferences.

You will find them here:
/Users/yourHomeFolder/Library/Application Support
/Users/yourHomeFolder/Library/Caches
/Users/yourHomeFolder/Library/Preferences

Not sure if you have to do this, but I did a Safe Boot after this, to clear some additional cache files.
