SimCity3000:Unlimited ---- Building-architect: NO-CD crack??

[Firecracker]

Hi all,

I was successfull in making a working backup of SC3U, but there's still ONE MORE THING wrong with it:
The program to make your own buildings doesn't work:
when I try to start it up, I just get the message that I have to insert the correct CD.
I'm no genius when it comes to this stuff, but I'm sure someone here knows how to help me?? Plz, pretty plz??
