#1 Post by doran_lum » Fri Aug 14, 2026 2:47 am

Hi all, i have email svq@makemkv.com with the error below but I have not heard from them.

Any idea what else i could try for the error below ?

Automatic HK downloading is disabled or failed.
You probably need a VPN to bypass the geoblocking. Or try to use KeyDB. (Extract the cfg file to C:\Users\Admin\.MakeMKV.)
