iPhoto 6 is not opening library
I'm using a G4 with OS 10.4.11. Five libraries are all stored on an external HD. Four of them are no longer recognized by iPhoto 6. cmd + alt opens the repair menu, but all functions (create thumbnails, create new database, etc.) are not executed. The iPhoto surface stays blank. Not a single picture, no album is displayed.
How can this be repaired?
