hi, i've got a book called 'accessing architectural desktop release 2 by william wyatt' bu the disc in the back is broken in two. This has a purchaseable student licence which i don't want, but i do want the exercises that are on the disc so i can learn through the book. I've asked autodesk press if they have another but they say it's too old. Has anyone got the exercises for this book or for that matter a disc they don't use, maybe because you've upgraded?? Appreciate any help. thanks
