Flex adobe book: broken cd... now what?

As topic..
I bought Adobe Flex 4: Training from the source book approximately 6 months ago (give or take a month), since I had half-a-mind of learning flex in my spare time..
As it turned out, I'm now in need of learning it (or at least I'll need to do a quick drill of basics + cookbook)..
I've asked my mom to send the book to me and.. Either she didn't pack it well enough, OR the postal service handled it poorly, or for all I could know the cd was like that for months (it was on the bottom of a pile of books :/) but fact is that the cd is broken, literally..
Since to speed up things I preferred a by-example/progressive-building drill, I'd prefer to learn flex from this book, but without the cd with the source files I'm quite locked out..
Do you know if adobe (like other editor) offer the chance to either buy another copy of the cd/get another cioy of the cd shipped/download the cd from a mirror?

Thanks in advance,
