Hi, I recently bought sims 3 generations. When I went to play it in live mode the screen keeps freezing every 5 seconds. I can still hear everything going on e.g if sims having a conversations I can hear them talking. But everything freezes. Really frustrating and makes it unable to play. I have sims 3 ambitions as well but didnt have to freezing happening with only that. How do I make it normal?
