Window Movie Maker keeps crashing.

Hi, I am wondering if you can help me with my problem with DVD Maker as it keeps crashing when I upload a video file and try to customize the menu. I've received these 2 error messages:

Any ideas? I do have a number of other DVD making software on my computer so it could be one of these?

Many thanks.
