Hello,
I downloaded the Passkey program and installed. I open it with the disc inserted. This is the info I get when opening the settings window:
Info for drive [D:\] (DVDFab Passkey 9.3.5.4)
Vendor: HL-DT-ST, Product: BDDVDRW CH10LS20
Revision: 1.02, Vendor specific: 4
Drive region: 2 (RPC II), changes left: 4(user) / 4(vendor)
AACS v1, AGIDs: 1, revocation level: MKBv65+
Support: BUS_ENCRYPTION=NO BN_GENERATION=YES
Disc media: Blu-ray (BDMV)
Disc is not opened.
I click in OK and after the trial period advise, program seems to start reading the disc. Then, nothing happens:

If I choose the option "Rip to hard disk" I get the message "DVDFab Passkey is not active for drive D:!". If I rip it to image with no protection, I get the same error message. But if I tick the "Keep protection" option, it starts ripping the image.
