New BlindWrite 4.2 - ProtectCD protection

Great Work!!!
But i have some questions.
What is with the new ProtectCD protection? Will this also work with BlindWrite? And what about with Tagés?
My last question. If I got a working backup, what must i do if i make a copy from a copy? Can i burn the copy with clonecd to get another working copy? or i must make it like with the original cd and Blindwrite?
