The problem is "amd 64".
The book.bin/books.bin files are _not_ portable to anything but 32-bit X86
machines. The problem is that the amd 64 makes the book structure longer and
that wrecks the binary portability of the book.
You are basically playing with a book that is corrupted beyond usability. I did
this a couple of time myself when fooling with the opteron system a while back.
your only choice is to download the enormous.pgn and start.pgn files, and create
your own books from scratch...
