They Live open failing - What am I doing wrong?

Trying to rip my "They Live" UHD

I've ripped many other UHD discs and haven't had a problem. But this one is giving me issues. It's new to me but not a new release. I saw a new hashed key database download recently so it's not an issue of not being able to communicate with other servers. What am I missing?

I've already submitted the dump but I figured that probably already happened since this isn't a new disc. Figured I'd ask here just to be sure. Wanted to make sure this wasn't a known issue.

As the FAQ states, there can be multiple keys based on region/re-release, etc... & it can sometimes take a while between dump submission & key availability. Generally speaking, be patient. Make an undecrypted backup, if necessary, for when the key becomes available.

Cool, I guess I wrongly assumed this release was old enough to be in the released HK list. No problem waiting.
