I have Windows Vista Basic Home and I had Pinnacle Studio 11 for video editing purposed, but after a while it stopped working, so I started using Windows Movie Maker. After I while I uninstalled Pinnacle and afterward Windows Movie Maker won't play the videos and no sound is played either. On Windows Media Player video plays, but no sound is heard. I recently uploaded Windows Live Movie Maker and the video plays on that, but no sound can be heard on that either. Can some one please tell me how I can fix this. Thank you.
