New version of unSafeDisc for v2.51.021?

[TLT]

I have Zoo Tycoon, and I wanted to make a backup....
I tried WinOnCD and it says the media is not authentic...
So I tried CloneCD, I have the last version...
Burned with my HP9300, with the amplifier weak sectors thing, and it gave a error... in the installation
So the setup.exe is protected, just like emperor battle for dune...
But only setup.exe, not the executable (zoo.exe), because I installed with the original cd and then played with a backup, but I can't install it...
It can only be a new update of safedisc2... i tried unsafedisc 2.40.010, with no sucess...
Lets hope R!sc can help us...
