Windows Movie Maker please help I am on a deadline

Good Morning,

I hope that someone can just help me as I have one week to put together this
movie for the parents.

I am trying to make a movie for someone , problem there are about 60 pics
included, 7-8 audios - and transititons between every pic ..now what has
happened yesterday and today is that Movie maker just crashes, I see the pics
Ive imported but on the time line they are just grey and then it stops
responding. Is that because there is such a huge amount of files?

If yes , is there a way around?
Am I doing something wrong?

And is there anything else I can use because I start slowly panicking now
and I dont want to spend an hour preparing it again just so it can crash and
I can start from fresh.

I have no idea how it all really works I am a trial and error kinda person,
so if someone also has some editing experience and could just help me (via
skype or so)

Please please please..

One desperate Bianca
