Windows Movie Maker Trouble

[RACECAR]

Ok so here's a problem I just haven't been able to figure out:

So I get on Movie Maker and I made a video earlier as well as yesterday. It publishes one video just fine (and in HD). I then try to publish another video and suddenly, it shuts down on me. I keep trying again and again and it keeps stopping. Can anyone help me out with it?

For reference, I have version 6.0( I hate the Windows Live Version):

Do you have Nero installed?

Do you have Nero installed?

Not that I know of, unsure what that is but it doesn't matter now. I just got through making a video and it published fine. Seems like the video I was using before might have been a format that WMM didn't support or it was too big(not sure which one). Either way, It works again!
