UNABLE TO BACKUP FLIGHT SIMULATOR 2002 PRO WITH CLONECD OR CDRWIN

[shooters]

Hi!
Could someone tell me how to make a backup of this soft (FS 2002 pro ,3cd)
I've tried with clonecd : Backup is successfull but the cd is empty!
I've tried with cdrwin : backup is ok, cd contains files, i launch the install and a message tells that the cd can't be identified

Did someone already performed a successfull backup oj this soft?
If yes, PLEASE tell me how.

Thanks in advance
