I too am having problems with install of 5. I on Firefox get the following message:-
Firefox can't establish a connection to the server at 127.0.0.1:23119.
The site could be temporarily unavailable or too busy. Try again in a few moments. If you are unable to load any pages, check your computer's network connection. If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.
Firefox is accessing the web, I can do a google search, so yes is connected to web? The only thing it seems I CAN'T access is the Zoreto server. I am going to keep trying, but.... any other suggestions?
