Installation problems

Hi guys, i have just purchsed SH% but are having problems getting the gameto work, any help would be appreciated.

The game has intalled fine but i cannot get the uplay to connect at all. Ive tried disabling my norton and opening ports to name just a few, but nothing seems to work. No other games or apps have any problem connecting to the internet. I cant seem to find any solutions to fix it online so im wondering if maybe there is some kind of workaround via patches and stuff.

Im a big silent hunter fan and am keen to get into this one, looking through the mods im expecting a good time, but simply cannot even get the vanilla game to run correct ...... help please!
