I've created three very short movies of a black screen with some audio dubbed over. Used Movie Maker as told it was an easy way to edit an audio clip I had.  Any way, project is saved but when I go to Save Movie and save as Audio only the pop up says "Saving Movie: Step 0 of 2 complete 0%" and then doesn't budge. Nothing.  I've tried saving it as other file types (i.e. not audio only) and the same thing occurs. Please help (in easy language), have already lost hours on this.
