I'm using UltraSurf (10.17), it used to work fine but now its not working on my computer (Windows 7) and the window keeps showing "Connecting Server..." and after sometime, it fails to establish the connection. While, its working perfectly on the friend's computer on the same network. Any help will be appreciated. (Please note that using Proxifier would be my last option if I can't get UltraSurf working anyway).
Check the "proxy settings" in the options window.
You will find a proxy setting button. Enter "proxy host" and "proxy port" like those that normally work for you.
