When I press the play button in Sims 3 town life stuff its working but when the introduction is done

Did you digitally download the game in Origin, or did you buy a physical copy? If you have bought the actual disk, then you have to insert it before starting your game up. If you bought the digital copy, then it should work just fine, but sometimes it seems to glitch out for some people, just reinstall it, and it seems to fix the problem most of the time.
I'm sure you have the base game, but just in case you're unaware(anything can happen); you need the base game for any of the stuff or expansion packs to work.
On the other hand, if you did not pay for the game, and downloaded it illegally (pirating), then you shouldn't even bother, you should just go and buy the original game.
