Command + E no longer does anything

So I accidentally deleted my prefs with an app called Preference Manager (was trying to only delete them for Adobe Encore which still remains broken). Anyway I can no longer press command + E to export a file. If I look at the SHARE drop down menu, Command+E is no longer next to Export File. I went into the customize thing (which I don't know anything about) and pressed command and E and it said "export with default options" so it thinks it's there but it's not there. How to fix?

EDIT:
Fixed! The problem was that I'm an idiot. I went into the Add Destinations box and right clicked the one I wanted to be default and chose MAKE DEFAULT. I'm leaving this here just in case it happens to anyone else.

Cmd-E is unassigned. In Destinations prefs if you set a default share function by right-clicking it Cmd-E gets assigned to it.

P.S. Use Preference Manager to backup and restore save preferences.
