They probably added 400 million more anti-cheat scanners to their single player game. Send Ubisoft your regards.
i agree with pwizard. ubisoft has probably added new "anti cheat" scan to the game with the patch. i have a issue with syndicate that is *NOT* related to the trainer (it keeps ask for the dvd even considering you only need it to install the game and no its not a "suspicous source" copy) so its yet another bug fest..
