i just installed sims 3; when i start up the game it loads fine but as soon as it gets to the game and small box pops up saying it can verify if the disc is a valid copy of sims 3. Then it goes completely out of sims and back to the desktop. I am playing this on a mac, dont know if that has anything to do about it

see if caspinwalls post here can help you (the 6th one) sadly at the moment we don't have a mac player/to assist
or try the mac forums in the TS3 site http://forums.thesims.com/en_US/categories/mac-discussions
