cannot add to favorites

Using IE11 with Win7 64 bit.  Cannot add a page to favorites.  Cannot import or export either.  When I try to import or export I get to the window that says" Import/Export Settings"  "Select the folder that you want to export your favorites from" the window is empty.  Also happens with Import favorites.  Window is blank, no folders to choose.  It's like Favorites is lost or disconnected.
