Idk what else to do really, im in early renaissance era and I've built every building that provides defense and/or reduces crime in most of my cities. There is nothing else i can build ... im at 16 unhappiness from which, 15 is just crime ... I even have a wonder or two that reduces crime in all cities ...
Out of 16 unhappiness, 15 is caused by crime??? As Funak says, you are not supposed to have 0 crime, but this seems odd. I'd expect some significant unhappiness caused by poverty and other sources. As matlajs says, it could be a botched install or a mod conflict.
I suggest you tell us more about your game and post screenshots.
