Windows Live Movie Maker keep crashing on publishing/creating.

Hi, i have currently made a project that i want to publish on youtube.. It keeps being stuck on Rendering, then i click on it, and it crashes. This happends with all render options. Any idea what i could do to fix this? I'm using the latest version of it.

at what percentage does it stop ? are you using any flv , mp4 files within your project and what's your final output format and settings ?
