"Program Not Responding" Message

Every other time i download CC and add it to the game, when i go to launch it itll freeze at the sims4 screen and then "program not responding" will pop up and i have to end the program. Is this due to creators not updating their CC??? and if so, why are so many creators not updating their items??? it really is upsetting to see so many good items be broken. I hope this isnt the case if anyone knows anything please let me know thank you.
