I know I had the same problem, no mention of it before I purchased it and bought it because as it was a game that was only 4 years old thought it would work. I am now trying to get a refund back from Ubisoft but not having much luck. You would have thought that if the game is 4 years old and it was inherent problem that they would have been some caveat on the 'purchase now' screen! Not happy!
