Select "Register" (even if you are already registered).
Immediately click OK without changing anything.
Watch the log window. You should see a prompt like: "Downloading latest HK keys..."

No. The message is purely informational. It does not mean your software is "disabled" or "failed" permanently—only that the automatic key retrieval engine failed. Your existing installation remains safe. You are not being hacked, and your disc drive is not broken.

7. Prevention & Best Practices

Keep automatic HK downloading enabled unless truly offline.
Update MakeMKV every 2-3 months.
Periodically clear _private_data.tar if you notice new discs not opening.
For automation (e.g., headless Linux servers), run:
```
makemkvcon --cache=/path/to/cache --minlength=0 info disc:0
```
This triggers HK download on first use.

VPN/Proxy: If you are using a VPN, try disabling it temporarily. Some VPN IP addresses might be blocked by the MakeMKV servers.
Firewall: Check your antivirus or Windows Firewall settings. Ensure that makemkv.exe is allowed to make outbound connections to the internet.
