Windows movie maker question?

i'm trying to publish my video as a wmv format, but the piece of sh*t movie maker always stops at 15% and gives me this bullsh*t message:

"Windows Movie Maker cannot save the movie to the specified location. Verify that the original source files used in your movie are still available, that the saving location is still available, and that there is enough free disk space available, and then try again."

all my sources are still available, the saving location is available, and i have A LOT of disk space. the space required for my video is 47.85 MB, and i have 253.04 GB worth of space available in drive c: on my laptop. if it matters what image and music formats i used in my video, the audio formats are wmv and wav, the video i used is wmv, and the image is bmp. it also seems like the cpu usage is task manager goes up really high around the 15% mark, and thats when it stops, SO WHY CANT I PUBLISH MY DAMN VIDEO?
