I am aware that there is many posts and replies regarding to this problem, but I only could find two things that could be a solution to this problem: -NET Framework -Disable Antivirus/Firewall However, updating to latest NET 4.0 and disabling antivirus/firewall seems to not be helping at all. I don't know what to do from this point, and I'm pretty sure everyone is experiencing same problems.
