@Girlielou Your CC is gone, unless you have a copy of your original Mods folder somewhere on your machine. You have had multiple Mods folders because, I think, you’ve been moving the Mods folder out of the default Sims 4 folder which forces the game to produce a new one. The new one will be empty. If you then move that new one to the same location as the original Mods folder you moved (dekstop) the OS prompts to Replace or Keep Both. You chose Replace which replaces the old Mods folder with the new one, wiping all previous data.
Your opening post is a little confusing. I don’t understand “I took out my mods folder everything was fine, took out the source and then put my mods folder back” (what source?) and “when I do Electronic Arts> Sims 4> Mods, it has me press mods again” (what are you doing and what are you pressing?)
