The Sims Life Stories crashes after few mins in the game

Hi guys. I love this site, it's always so useful. Anyways, I looked up for this problem but it seemed like no one posted it about. So a few weeks ago I installed Life Stories cause I really wanted to play it. But whenever I play it (right now I'm playing Riley's story) it causes "stopped working" message to appear. Anyways I think no-cd crack would help, but idk where to find it, and I'm scared of viruses . Do you maybe have a safe link for it or something?
Thanks
