Use infinity a few days ago and everything worked fine. Today, 4/24, error code 13 pops up when trying to use cheats in Assassins Creed IV. Have disabled AV and AS and tried running infinity in admin. Error code still pops up. Infinity works fine on other games.
It is your antivirus. Add the game and infinity to its exception list and then try.
What is AS ? and which av you are using.
AS is anti spyware. AV is Panda. Both the game and infinity have already been added to exception list. Cheats still did not work. Did some more playing around and managed to get the cheats working but only when Uplay is offline.
