LOVE YOUR PRODUCT
I will purchase the moment the beta program ends

This is my first error. Hope I am posting any useful data:

Can't read AACS VID from disc - most likely current AACS host certificate is revoked by your drive
Highest AACS version is v58 , MKB saved as MKB_v58_The_Forbidden_Room.tgz
The volume key is unknown for this disc - video can't be decrypted
Failed to open disc

What version of MakeMKV are you running?
