With vbox 4.1 a new version 2 was introduced which cannot be used with an older vbox version. So have you probably created a snapshot with a newer vbox 4.1.x and then switched back to vbox 4.0.x and restored the snapshot there? If that is the case you can restore the snapshot with 4.1.x and be sure that there is no saved state anymore and then switch back to 4.0.x. -- Bernhard Fröhlich http://www.bluelife.at/
