iPhoto videos won't all load
I have been using iMovie 11 (version 9.0.9) on OS X (10.7.5) for a short while now and have never had any issues seeing my videos from iPhoto. However, when I went to start my latest project, iMovie had trouble seeing all of my videos from iPhoto. It asked to create new thumbnails but now the only videos that show up are older videos (2004-2010). None of my recent stuff is showing up anymore. I have searched the threads and found several about fixing "bad" thumbnails, but nothing about only seeing certain vids. Is there a limit to the number of videos that can be displayed? If anyone has had this happen, or has any suggestions I would appreciate the help.
