I just downloaded V1.9.1 and when I try to rip a BluRay, I almost immediately get "Evaluation period has expired, shareware functionality unavailable. Failed to open disc."
DVDs rip OK. This always worked up until now.
I am using a Pioneer BD-RW BDR-208M unit under Windows 7 64 BIT.
I have rebooted, reinstalled, etc to no avail.
I looked for problems like this in the forum, but I see none.
Am I forgetting something?
Thanks,
Joel

After poking around a bit, I remembered I saw in the general discussions about a beta key, so I figured I would try pasting that key into the registration field and it now works OK. I never had to do this before, so I was a bit puzzled about this problem.
Is this a change in the way MAKEMKV is setup to work from now on?
Thanks
Joel

It's been this way as long as I can remember.
