I import my files, put them together to make a music edit, then the music just replays the first word over and over again. I restart, restart my computer, Camtasia, everything. And when I go to save the file to save the file, it says, "This file cannot be saved as, "MusicEdid.Cmproj". I could use some help. But it saves all of my other projects, and I create a new file to restart the project, and nothing works.
