Query: Book looks great, but faulty DVD-ROMs and lousy service

If I ever get working copies of the two DVD-ROMs included with this book, I look forward to actually starting to use it and giving a better rating. But so far, it has taken weeks of emails to receive ONE of the two replacement discs, with no explanation or indication of whether I will be receiving the other one. Apparently there is occasionally a bad batch of discs, so check as soon as you get yours that all the files copy across to your computer correctly.
