Try searching your hard drive or server for *.sai. Another possibility is you may have inadvertently saved to Microsoft's one drive. Have done this myself.

Thanks for the info.  I tried one drive. Nothing.  It is strange that I have only lost one "sai" file, and all my other clients are still there.  I am afraid to restore my backup, as then I won't know where to begin to confirm what I have posted since that date.
