I had bought the Sims 3 pc game about three months ago and then I bought Sims 3 Late Night. It had been working before but after a few weeks of not playing it I try launching it, getting it ready so that I could play it, but then all of a sudden it says that my disk is uncompatible and that it needs to be updates. But both games have already been updated. What do I do?????? Will I have to re-instal the game??
