Imported images no longer in appearing in viewer
Hello,
I have just updated the latest software update OS X El Capitan. Since the update, when using iMovie '09, the images I imported are no longer visible in the viewer when I skim through or play my project. All I'm getting is a black screen where the images should be. I can still see the images in the project editor, but if I were to export the project the a movie file there is nothing but darkness. Strangely the text that I have edited onto the video is still there, but once again, crucially, the images are not.
Why is this? Has something changed in my preferences? How do I fix it? I have a lot of projects to do and deadlines to make, so any advice would be gratefully received. Many thanks!
