Just to re-iterate JRW's post, this is not a forum for passing on information regarding illegal practises.
You will not find any of the regulars here are willing to entertain the idea of passing on, or disclosing information about, pirated software and the like.
If you wish to copy your authorisation disk for genuine back up reasons then, as JRW stated, there is no need, your local Siemens support will gladly help you recover genuinely lost authorisations, that is, if it is liscenced to yourself or your company in the first place.
I am by no means accusing you of illegal practises, I merely wish to point out that pirated software etc is not condoned on this site.
