Brilliant, thank you! I was starting to fear I'd have to recreate it from scratch.
EDIT: Well, I just found the non-corrupt original .mpg file, because I kept searching my computer for the word sabre and the corrupt version would always come up and thanks to your upload I knew to search for lightsabre instead. I just thought if I looked for sabre +.mpg, anything with lightsabre would automatically come up as well - apparently not. What's even weirder is that when I searched for Luke +.mpg, it hadn't come up either but as soon as I searched for the word lightsabre, it came up instantly.
