Problem with WMM and WLMM?

okay, so I made a movie for a school project in Windows Movie Maker 6 and when I'm having it published, a freakin' problem occurred... the loading stopped at 79% and it won't load anymore. I tried restarting, uninstalling and reinstalling, publishing it for how many times, nothing worked. So I switched to Windows Live Movie Maker (Windows Ultimate 7) and made my project in there again. It got published, but the movie's quality was crappy. The sound was late and, the scenes and pictures sticks. I've tried the same ones that I did on Windows Movie Maker 6 but nothing also worked. How can I have my video published in either program? I really need it to be published, seriously. I don't want another program or software to have it published because I made that video in a week and it was more or less 20-30 minutes long. So spending time doing a compiled project that only needs to be published again in another program will drive me insane...BUT if there's a program/software that converts a .wmlp or .wsmm files to it's specified file type and lets me publish the video there, then I should get that program; please give me a link where to download the program. I really need to publish it, I'm more or less a day far from the deadline.
