NOTE :  This trouble has been fixed in version 6.01.  A warning message now appears if there is not enough space on the target storage medium during the archiving.

This trouble can only be caused by a truncated ".sez" file.  During the archival storage, the location where the ".sez" file was created did not contain enough free space (like a 1.44MB floppy disk).  So the ".sez" file has been truncated to the maximum available free space and no error message has been reported.

To avoid this error, always specify a location that contains a lot of free space (like your hard disk), then copy manually the ".sez" file to the target backup storage medium.

In that way, if the ".sez" file can not fit on the storage medium, Windows™ will notify you.  To make the ".sez" file smaller, simply put less scenes in it at a time.
