My sims 3 game freezing (PC)?

OK so a few days ago my sims 3 game had an update and with that update it made me download origins Beta after that my sims 3 game stopped working. when ever i go into my game the first few seconds it freezes. I have uninstalled and reinstalled it 3 times and then i installed it using origins which took 6 hours (wtf) it barley took me 30 mins before. The game is still not working. Does anybody know whats wrong with my game.
