I think you best course of action would be to contact the publisher. The reason you probably not getting any volunteers is either a. they don't the book nor CD or b. they don't want infringe on copy rights by copying and redistributing the CD. Just my hunch. The problem is that it is too easy to get books electronically theses days so there are numerous illegal copies floating around. While I'm sure such isn't the case for you, the truth is there is no way for anyone online to be 100% sure. Hope this helps.

Since this is an alias press book it should be simple matter to query their support staff about this. They may charge a nominal fee to replace the CD or require proof of ownership, but if you really want the disk then this shouldn't pose any problem.
