Lion & Mountain Lion Compatibility
Unfortunately, Apple has decided to remove any binary that is not a default part of OS X from the /bin folder on your system during updates to both Lion and Mountain Lion. This results in the ArGest binary application being removed causing ArGest Backup to either report an invalid install of the incorrect version of ArGest.
To resolve this problem, reinstall your current version of ArGest Backup and all will return to normal.
