aperture 3 freezing when adding audio
I'm running Aperture 3.4.5. When I make a slide show with only pictures and video, it continues to work fine. It is only when I add audio to the project, whether it is from my itunes library or preset audio from the program, the program freezes and I cannot continue. I have to force quit to get out of the program and restart. I've tried opening a different library altogether, reinstalling the program, and importing audio directly into the program (drag and drop an mp3 file, which shows up as aperture audio file) and it continues to do the same thing.
Any thoughts anyone? Thanks for the help......
