copy of backupCD

[Hugo]

Does anybody know why I cannot create another copy of my backupCDs?

I used clonecd ver. 3.2.1.0 to create a backup of my CD, but now I can´t make another copy of this backup CD because clonecd just won´t read it (tried it as well with the default ProtCD settings as with the settings recommended by this site).

Thanx for your help ;-)
