I had films and Music on my Windows 7 computer and had already made a film from these but since getting a new laptop with windows 8 on it I am not able to make a film with the same files that I had previously used I can get as far as a project and it gets about half way through stage 2 of making the film then I get a message windows movie maker has got a problem and has to shut down with no explanation of why and it is most annoying as I am not sure what I am doing. the videos from camcorder are showing AVCHD Video (.MTS) and the music files are MP3 File (.mp3) can anyone help
