Crashed .sim files

[Lothlorien]

Hello,
so i've been playing with cc for a year without any problem and yesterday i downloaded new sims for my game. i put .sim files to the savedsims folder and opened game but cas screen is not loading. i deleted the files from that folder and there's nothing wrong. now i can't find which .sim file is crashed. some of my sliders are not working too. what can i do to find crashed .sim files and why isn't my slider working? thank you.
