Organizer won't open

If you press the Shift key while launching the Organizer, the Manage Catalogs dialog should open.  Create a new empty catalog and see if you can open the Organizer with it.  If you can, try going back to the File>Manage Catalogs dialog and try repairing and optimizing the original catalog if it is available.  Upon completion of those operations, see if that catalog will open in the Organizer. 

If that doesn't work, lauch the Organizer with the Shift key pressed and open the new empty catalog again.  Go to Edit>Preferences>Media Analysis and uncheck all boxes.  Then  return to the Original catalog and see what happens.

And before doing any of that, I suppose I should ask whether you attempted to convert what I assume is your version 12 (not 2012) catalog.  Or did you create a new catalog upon first launch of your Christmas present?  How did you import (upload?) files into that catalog?

What happens when you try to open the Organizer?

Is there an error message? If so, what does it say?

What operating system?

If Windows, can you open it directly from the exe file in Program Files?

I've moved this from the Using the Community forum (which is the forum for issues using the forums) to the Photoshop Elements forum so that proper help can be offered.
