Long night ahead

This afternoon, I carelessly hit the "Revert to Snapshot" button on my
VM that I was working on today. Although it was cup day I had
installed the new version of the product and made some serious inroads
into the design of the main interface. However after the careless
button clicking BLAM back to the previous version and bye bye to all
the changes... And yes... all my backups of the system design were on
the VM...
