Contact Info for Ccleaner
You posted previously in a thread about geo-location blocking.
Is your CCleaner also being Geo-blocked?
Whereabouts in the world are you located, which country?
As said in that other thread if you are being geo-blocked by mistake then sometimes turning your router off at the power plug for a while can fix it by giving you a new IP address when you turn it back on again.
However that will not work if you are in a country that is being geo-blocked. So we need to know what country you are in.
