Recreate Issue
During the save process, delete or overwrite the media you used in your project. If the file is missing, you will get this error.
Resolve Issue
  1. If you are using an AVI or other media file within your project, make sure you do not try to overwrite the file with the saved project file; they should be named differently.
  2. Make sure all project files are in the directories listed in your project. It is always good practice, to keep the project file within the main or sub-folders. This make for easier organization, and cuts down on render related issues and mishaps.
