Windows 7 - Movie Maker stops when I load AVI files.....?

If this is in the work location I apologise. This is my first post.

I've just installed Movie Maker, & it stops when I try to load some AVI files (a flight sim flight) I've made using Fraps. I can load photos alright but not my AVI files. Can someone tell me what the problem might be or what to do?
Thanks

Well,Windows Movie Maker is not a non-linear editing application and it only supports wmv and certain mp4 files,Fraps record in avi which is compressed to the core unlike the other avi files.
I suggest you that you get Sony Vegas xx,or convert the avi file to wmv.

Thanks. I'll have a go at it.


I wrote work but meant wrong by the way!!
