I get "401 Unauthorized: Temp URL invalid" when trying to download

Your service provider constantly changing your IP address and our security system reacts as if your account was hacked and blocks the link.
We recommend to use VPN such as:
CybergHostVPN.com (has a free plan)
HotVPN.com (Have to buy) it is working good and easy to use.

Also using a Public Proxy Server (e.g. public-proxy.blogspot.co.uk) might resolve this problem. Proxy setting can be defined under your browser network or LAN settings.
