As there is no Windows 10 20130 build I would suggest getting your hands on eikther a Windows 10 Preview build 10240 (the RTM build) iso file or better yet upgrade a valid windows 7/8.x license to official.

When Rohan client attempts to log into its authorization server using the https (ssl) web protocol. Some applications ytou can run iknterferes with that like skype and VMWare since they install their own servers on the ssl port 443. This causes problems when the login.playrohan.com is redefined in your hosts file to point to 127.0.0.1 (something that happens when you play on private servers to bypass clients 'phoning home').
