I am trying to make a movie from a couple .mp4 videos from my Windows phone.  Transfered files to Dell desktop: Windows 7, Window Essentials with Movie Maker 12, Nvidia GeForce Go 7900 GS graphics, 4 Gigs Ram at 2.0Htz.  

The program works well through the editing cycle and saving "project" files .wlmp.  Stupid thing shuts down everytime I try to "save" the movie - no matter the resolution.  The error is:

I have reinstalled Windows Essential and Navidia drivers.  

I remember having this problem and wasting a bunch of time the last time I tried to use Movie Maker - but it seems it would save one out of 3-4 tries.  Or, I might have given up and used some "freeware", but it was much bigger than this job.  The video is only 1min29sec.

Help!   Thanks...
