I am using Assassin's Creed 2 PC version. I've installed the game. Whenever I start the game, an error used to occur saying "an internet connection is required to run the game". I contacted the production firm, they asked me to delete host file from windows and change the proxy host name and port in settings.ini file to my proxyhost and port name. The error for internet connection did vanished but a new dialog box appears asking to register atleast once on web through uplay account but does not recognizes the presence of my internet connection. It asks me to register online but doesnot accepts my registration and neither detects my internet connection. Kindly help me with it as the manufacturing firm replies hopeless solutions.
