Ok, I'm usually playing on 360 or ps3, but I decided to give it a shot on the pc. I bought the Assassins Creed 1&2 Encore pack. I installed it and signed up for Uplay. It begins to start the game, I see the UBISOFT logo then the next screen....then it kicks me off and goes back to the UPLAY screen. Says Ive played 55 secs in this session. What gives?
