Disk Juggler and e-sscope.cdi

Hi
i have Silent Scope(on import)and a backup which i acquired from a very capable crew called echelon recently .
I have unrared it (the checksum is correct!!)
but when i go to burn it in disk juggler the file isnt reconised and the start burn button isnt enabled.The unrared file is a .cdi
The only prog that seems to burn it is fireburner which burns as an audio file, which then doesnt work in my dc. Does have anyone have this release or any other Disk Juggler/echelon releases? and do they know anything that i might be doing wrong?
Or if anyone has a checksum sfv for a known working dump of this release so i could compare.
I have a Boot disk that burned succesfully using disk juggler so i know disk juggler is fine.
I feel obliged to say that iam NOT looking for isos or any other releases by echelon or any other "warez" group .Iam simply looking for information on backing up a very expensive import because as everyone knows it does not take much for a DC game to get scratched and there for not work anymore .
I hope this message isnt misconstrued , i do not wish to promote piracy or harm the games industry and iam quite temped to say blah blah but i wont.
Thanks in advance for any help

p.s nice to see this forum backup!
