There has already been quite a lot of discussion about that error message.

thanks for link, in my case problem was found in missing tag "HardDisk uuid=" in .vbox file, probably for corruption of file on shutdown.
I restore it from an old backup and with some adjustments of Snapshot uuid, now it work perfectly.

Ciao,
