Lately when importing movies from Sony Handycam video loads correctly but audio appears to be missing and can't seem to find a way to make the audio work.  Has anyone else had this problem?  What may I do to resolve this issue?  I'm operating using Windows 7 and using Movie Edit Pro 15.  There is also a problem (which may be connected) with editing the movies.  When I go to edit the imported movies, the screen does not show any of the clips imported, nor does it show timeline for video/audio to allow editing.
