DVDFab HD Decrypter not detecting HD drive

Hi, I’ve tried HD Decrypter on my two PCs. One is a laptop with an inbuilt Toshiba HD-DVD drive and the other is my home PC with the Xbox 360 Driver installed. Both play movies perfectly but the HD Decrypter doesnt detect the drive on either machine.

Anyone have any ideas? I’ve tried Auto and the other driver software options in Options.
