After working on it for a while I also decided to move some of the original photos and video from the desktop and into my "Pictures" folder.
I went back after moving the pictures and half my video was black! Soooo ... I have gotten most of it back to the way it was but it took a very long time.
I was wondering if this happened because I removed the pictures from my PD library or if it is because I moved them from their original source? Or because I removed them from my PD library AND moved them from their original source.
Anyone know?
