I got the sims city living expansion pack today and ever since I installed it, my sims hasn't been working. It keeps coming up saying 'the sims 4 has stopped working' every time I try and load onto the sims.
Same, i have just got it and i can load them game, but i won't let me access the new world.
Try resetting your user files as described in the factory reset described in this post: http://answers.ea.com/t5/The-Sims-4/FAQ-Troubleshooting-Steps-amp-Known-Issues/m-p/3621199
You won't loose anything. Just make sure to not delete any files and make a backup.
Try on a new game with nothing added back first (start new game). If it works, put back your save game and try again. If it still works, you can start putting stuff back.
The rest does not need putting back, cause they are mostly cache files that recreate or log files that are not needed for the game.
