Did you create the .bkf file on disk and then burn it to CD using your CD
burning software? Drag/drop/explorer view CD burning is very error-prone and
I don't recommend it for much of anything.

Did you choose 'verify' on the backup jobs? This is a must....& check the
backup log files, too. I hate to say it, but your backup files may not be
any good.
