I am running the latest build of Sony Vegas 13 and usually edit videos using it. Just recently my Sony Vegas 13 Program would start "Not Responding" once I dragged in media from the timeline! I have restarted my computer nothing changes! I have looked at Youtube videos and try all there is with the preferences and video tab and turned off my "GPU acceleration of video processing" I truly don't know what to do so my last resort was to come here and ask for help. Thanks!
