It’s a long time since google removed Market Unlocker from google play. Recently I’ve been reported that it does not work fine because google play was upgraded automatically and silently to detect IP address as well as carrier.
Users will have to configure and enable a proxy (USA proxy recommended) via which access google play beside enabling Market Unlocker.
For pro users in some countries, they found fetch USA proxy not working because the proxy index server was blocked in their region

You may try another proxy by re-fetch proxy, or reboot phone. Google rejects refuses some proxies and also it may cache the no-connection error. And if still not working, please send me email directly. Thanks.
