Why is SocialVPN not accessing the web interface?

Question

VPN

Hello, there was a need to raise a VPN for shared network resources and toys, the choice fell on SocialVPN, but there was a problem, after installation and launch, I can’t enter the web interface for further configuration. on the site they write that you need to go to the address 127.0.0.1:58888 but the browser says that the page is not available. Tried win 7 x32 win 8.1 x64 and different browsers, chrome, opera, ie. The result is the same. I really hope for your help.
