I have searched the forum and chatgpt. I have downloaded keydb.cfg and put it in the directory folder and restarted and still nothing.

Not sure what's going on. It's a brand new copy.

Read the Hashed Keys section of the UHD FAQ.

Also, please email your dump to svq@makemkv.com.

There's an alternative key mechanism that you could try called keydb.cfg (https://forum.makemkv.com/forum/viewtopic.php?p=162444#p162444)

I emailed the files. Before I posted this, I tried the alternate keys, but they didn't work.

The KEYDB.cfg file is a "fallback database", which MakeMKV can use (if available) when it cannot find your disk in its own "hashed keys" database. But there's no guarantee that KEYDB.cfg will contain your disk either .

Emailing your TGZ dump file to svq@makemkv.com allows MakeMKV to add your disk to the "hashed keys". Also providing your dump here potentially allows The Power That KEYDB to add your disk to KEYDB.cfg too.
