Hi, I just used v1.4.9 to rip a disc fine. I then thought that I would check for an update and installed v1.4.11. Following this I had the error "Cannot obtain exclusive access for optical drive" on both my internal and external drives. I tried reverting to the older version but then had the same error there. I've never had a problem with this before. I haven't done anything to change my system in between. Any thoughts?

Had same thing but usually just eject the disc and have makemkv running (close and reopen it first though) should do the trick. Obviously if you have virtualbox running that'll lock the usb bd drive to windows.
