I have just fixed this problem about a few minutes ago, and it was very simple and quick. What you need to do is right click on the game picture and it should say update/repair game, I did the repair game and it only took about 10 minutes
Easier way to do it is left click the game and click on "Repair" worked perfectly for me every single time hope this helps (even though its 2 years!) anyone struggling with this Happy Simming
I went on a chat with an advisor and she told me to,
right click on the game and click repair game.
once the game had completely repaired you should be able to play the games again.
I should tell you now that this takes two stages of loading, for m the first was fast and the second fairly slow.
Hope that this helped you,
