Basically I was cc shopping for sims 4 and I tried loading up my game but an error message popped up reading "cannot start because the below file appears to be corrupted. If this file is a mod please remove it and try again. If not, please repair or reinstall the game via origin." I have deleted the custom content file that it says, I repaired my game and reinstalled it but the same error message still appears when I try and load up the game. Any ideas on how I solve this problem thank you!

I would start by clearing your cache files. http://www.carls-sims-4-guide.com/help/cache.php

Most likely another Custom Content Item or items that is causing the issue.

It can also be the browser you are using to download the Custom Content.

Moved to the Help forums ^-^

I bet something you downloaded is for sims 3 or you have an outdated mod.
