Mac randomly keeps restarting after installing game.

Hi guys,

I torrented Age of Empires and installed it as a .toast using I believe Disc Utility on my mac. It seemed to be running fine with some of the fonts being slightly off. but ever since my mac keeps randomly restarting at least every time I use it, causing a black screen and a message about something went wrong.

I've tried to uninstall the application, repair disc, repair disc permissions but the problem still persists. Is there any quick fix to solving this?
