Back at the beginning of June I downloaded device called 'Windows Movie Maker' to edit video's with and post them on YouTube. I was able to make a great amount of high quality video's with very few problems. I don't know why, but around the beginning of July something changed and has yet to fix itself. Whenever I try and save my edited video onto my computer it messes up. The video will start off fine, but somewhere along the line, it goes out of sync. I'll be sitting here shooting things in my video and my audio will be that of a minute before. It's incredibly annoying. I really want to make good quality video's for my channel and it's audience, but ever since July, I haven't even managed to put out descent one's. Please help me :(. I'm very short on money at the moment and I don't know if I can afford anything like Sony Vegas. Plus I really enjoyed using this program edit, it was always simple and easy. Thanks

p.s I have tried everything from restarting my PC to running cc cleaner to updating my graphics driver in geforce and nothing has worked...
