When I try to insert a .wma file, it says that this is an unsupported format. I am trying to edit an audio file, WITHOUT any pictures or videos. The older version, (Windows Movie Maker) allowed this for years without any issues, but I'm not able to do the same with Windows Live Movie Maker. Am I supposed to do something differently or does this newer version not allow audio editing? If it doesn't, please suggest some other programs that do, so I can download and use one for the same purpose.
