You can try using a VPN and connect to a US server (or a server in a Good Lock supported country) as described by a forumer a few pages back.  Or it could be faster and less painful to download NiceLock (from Play Store) and its NiceLock Downloader Companion (open Nice Lock app after install, go to XDA support thread to download this app as it cannot be downloaded from the Play Store) to download, install and configure Good Lock modules.
