For all those who having difficulties because of IP blocking, all we need to do is to find a stable Free VPN services that can bypass this such thing. So that until now I have not stopped searching for it to solve this problem.
I had found one, it was working fine with he free 3 day trial. I was able to connect to each and every server. Not even a single error message. And after purchasing it, the problems started. Now I am unable to find even a single working server among the list of servers. The vpn is working fine. no problem in connecting UK software with it. But US is gettkng error... I don't know what is wrong....
