I used to play this game with my father as a kid and wanted to start playing it again. When I did I got the this file is "damaged and can't be opened. you should move it to the trash" message. I see other people have gotten it to work with mavericks but i don't see a definite way to get it to work. I've tried downloading it and reinstalling it twice now and still nothing. Any one that has made this work could you help me? is there something i am missing?

Which system do you have? You need to give more information. Its hard to solve a problem from just getting, oh it doesnt work...

PS: post your problem on TAuniverse.com there are lots of competent people able to help you

You need to go to the security & privacy settings in system preferences and check the box that allows applications to be opened from anywhere.
