Problem with installing/setting up

I downloaded photoshop elements 11, installed it and ran in for a few days.  It ran fine.  Then it wouldn't let me open organizer...sometimes..then not at all.  So I uninstalled and re-installed, to no avail.  Now if it opens it at all I get a white bar across the top and then a white screen...and it freezes.  This should not be this difficult???
