Black exclamation mark when opening photos
I can not open my photos on my computer. The videos work just fine but eveytime I click on the photos I just get a triangle with a black exclamination mark. This happens both in iPhoto and in preview and I cant even search for the file name to find them. But the thumbnails are still there so the pictures are not deleted. In the masters file I find the videos but not the pictures and I have not deleted them from my computer. I've tried downloading iPhoto Library Manager but nothing is working.
My operating system is OS X Mavericks 10.9.1 and i'm using iPhoto 9.5.1
