Video Previews aren't showing?

    • Video Previews aren't showing?

      I use a program called Sony Vegas (9.0 Movie studio version) to edit videos for my family, like making slideshows or adding effects to things, but recently (in the last month) it has started to act up. It won't let me preview the video, and whenever it does it freezes during crossfades or practically every transistion except for fade out. Is this normal? Or is there anything I can do to fix this? Please help if anyone knows how?:confused:
