My Sims 3 Crashes

ive never really had this problem until recently and im not sure if it has something to do with the fix or a bug from the update but at the most random times my game will crash and a box pops up saying that it has stopped working unexpectedly. and this just sarted happening is when i open up the launcher it has started saying that.. any help would be great. i do own the base game, pets, and generations and all of the other ones are downloaded off of here except world adventures, i have been having a hard time installing world adventures as well. thank you!

Hello,

Do you have any Mods or Custom Content?

The exact same thing has started happening to me, except the message is coming up once I load a family to play not at the launcher. The message started happening closer and closer to when I started playing and now I can't play at all. I have no custom content or Mods
