Have you tried downloading the latest KEYDB.cfg file, copying it into MakeMKV's data directory (i.e. where MakeMKV also writes its TGZ dump files) and restarting MakeMKV?

works with latest cfg file thanks

I have the latest KEYDB.cfg file and am still met with this:

Given that KEYDB.cfg does already contain your disk's key, I can only suggest either:

1. Your UHD drive has not yet enabled LibreDrive.
2. You have not copied your KEYDB.cfg file to MakeMKV's data directory (i.e. "C:\Users\MyUserName/.MakeMKV" in your case).
3. Your KEYDB.cfg file cannot be read for some reason, e.g. typo with its file name, incorrect file permissions etc.
