I downloaded sims 4 from a new computer and now my files, not saves, are missing

First I got sims 4 on disc earlier this year, all the files were there, it was in the C drive, and origin had no problems. A week ago now I switched computers with my mom's old one. The C drive doesn't have enough space for sims 4 so it's in the D drive with enough space. It runs fine with my packs (seasons, cats and dogs, eco lifestyle, parenthood, dine out, outdoor retreat, laundry day, and tiny living, Tiny Living crashed origin though) the problem is that files that were there when I had it on my old computer are gone. This is what it looks like, from the top of my head mods, screenshots and screen capture are gone and even if I download my own mod folder (and put mods allowed) they don't work. I have no way to get my screenshots and nothing is helping, the files are gone no matter what. I've uninstalled and reinstalled, moved game, play base game, repair game, but nothing is working. here's sims 4 in my d drive.
