I had downloaded The Sims 3 and I followed the instructions. Then I played it and it was fine. I then bought The Sims 3 Late Night.I installed it, with following the instructions. I played it and it worked fine. I then put in the Sims 3 and it was playing like normal. The next day I tried to play The Sims 3 and it says I need to put in The Sims 3 Late Night. Also, that I was out of date when it says I am up to date. I want to play The Sims 3, and it tells me I have to play the Sims 3 Late Night. Now I can't play my Sims 3. Yet still when I try to play the Sims 3 Late Night it says I am out of date. When my screen says I am up to date. It was working fine then it failed and I can't play my games. What's going on? Please help me.
