I used to download music videos and movies on LimeWire and they used to be fine (with both picture AND sound). That was on my desktop PC. I downloaded the LimeWire program on my laptop which I'm using right now a while ago. The songs are fine but whenever I download a music video it's clear and all but there is NO SOUND. I've checked stuff like the volume and made sure that it wasn't on mute and all that but I think the problem is in the LimeWire videos themselves. Did this happen to anyone else? How can I fix it? Help.
