The following warning is thrown when archiving projects. I've tried each of the available flags shown below but nothing suppresses it.

Does anyone know how to avoid this message?

The message is thrown for all of the following.

vegasApp.ArchiveProject(projectName);
vegasApp.ArchiveProject(projectName, ArchiveProjectFlags.NoSpacesInMediaFiles);
vegasApp.ArchiveProject(projectName, ArchiveProjectFlags.All);
vegasApp.ArchiveProject(projectName, ArchiveProjectFlags.None);
