|It has failed to load the project file (.GRP) that I edited and saved.|
You may encounter an error about a project file (.GRP) not loaded if the source file has been moved or renamed.
For example, if you created a project by editing a video file "A" from the Desktop, the file "A" has to exist in the Desktop folder when you load the project.
If the file has been renamed as "A1" or moved to a different folder, the program fails to load the project.
Correct the "Path" or "File name" provided with the error message before trying to load the project again.
