Error trying to restore a domain from a backup

Error trying to restore a domain from a backup
I am getting this error when I try to restore a backup from my old server which whas FedoraCore 7 to new server running CentOS 5

Restore failed : The specified source does not contain any domains, or is not a Virtualmin backup

I can unzip the file and seems that all files are there but virtual min refuse to read it ?

Both systems are running Virtualmin 3.59 and are fully updated.

Closed (fixed)
