Just a thought?
Do try ''Isobuster'' to extract the files from the CD which by using would by pass the programing you are using.
It may Work, yet I feel worth a try?

Available to use ?Free? =
Find ?IosBuster? at http://www.isobuster.com/ [The Pro Version you have to pay for???].

After you install the program you will locate the Isobuster in the Quick Launch Bar. Insert your CD in the CD Rom Drive and open it up with the Isobuster program = When present on the screen right click on one of the Image files and select ''Extract....'' = navigate to ''Save'' same say to ''desktop'' = Then see if you can view the Image.
Hope may help??
