Sims studio Not saving changes made

Hi! I'm trying to edit a couple of things on some of my CC (like the object's name or swatch colors) but when I try to save the changes I've made it gives me this error message:  

The Sims 4 Studio - Version 3.1.6.2

S4Studio.Data.IO.Package.PackageLoadException: Failed to load C:\Users\[UserName]\Documents\Electronic Arts\The Sims 4\Mods\NumbersWomanUsedShabbyChicKitchenBreadLoaf-1214.package ---> System.UnauthorizedAccessException: Access to the path 'C:\Users\[UserName]\Documents\Electronic Arts\The Sims 4\Mods\NumbersWomanUsedShabbyChicKitchenBreadLoaf-1214.package' is denied.

I have no idea what this means or what I'm doing wrong. Can anybody help? Thanks! -Kelli
