I have Windows 7 ultimate on my laptop.  I'm using Window Movie maker as I have in the past for an end of the year DVD for my Kindergarten class gift.  My project file works great, but it is not saving into the movie maker file.  When saving in either file format, I only have audio.  The video screen is black.  All pictures and video are accepted file formats.  What is wrong?  The program is updated, my drivers are updated.  I don't know what else to do!  I've been  on this for a week and I'm going to give up and not use this program anymore!  I would love a magic answer from anyone out there.  Thanks!
I see a lot of questions about this, but no answers, WLMM11 stopped video screen black, only sound, I cant figure this out. Please help!!
