Iphoto will not import

Question

-I am runing iphoto 11 9.2 on an imac osx 10.72.  I had no problems until a few days ago when I discovered that I could not import photos from lightroom, camera or file.  I checked on line and found a lot of info on a plugin called 3ivx.  I searched for it, found a 3ivx pass list, moved it to trash with no improvement.
I also have tryed to rebuild photo library.  Now, i still canot import, but most of my thumbnails on events are missing and the photo thumbnails are also missing inside most of my events that were made prior to 2011.  If you click on a blank thumbnail, the photos are there. 
I moved my library to a external harddrive a year or so ago, using the name test with a master and alias in folder. 
Not sure what to do, thinking about unstalling iphoto and restalling but not sure that would help.
Attaching the first part of report to apple.
Any help would be appricated.

Answer 1

The Report refers specifically to the 3ivx issue:
__DATA                 0000000019987000-00000000199a7000 [  128K] rw-/rwx SM=PRV  /Library/Application Support/3ivx/*.dylib
Try trash the 3ivx folder from
HD/Library/Application Support
I don't understand this:
I moved my library to a external harddrive a year or so ago, using the name test with a master and alias in folder.
Moving the Lbrary doesn't require any aliases or such like. Hold down the option (or alt) key key and launch iPhoto. From the resulting menu select 'Choose Library' to point it at a library in a new location.
