IATKOS S3 - dmg verify Internal error

[brs65]

Hello,

 

I installed iATKOS S3 10.6.3 on a Dell Optiplex 755. .. Everything works except the restoration of images dmg. I can create my backup dmg image without a problem. But, when I try to restore the image I get the message "Unable to verify monbackup.dmg (internal error)

 

I update to 10.6.6 and the same.

 

I wonder if it comes from the kernel qoopz.1.3

 

Has anyone had this experience?

 

Thank you for your help, Bruno
