My Sims can't read correctly.. one drive..

Ok so I have a MASSIVE problem, which I made all by myself! :D 

Better ex always tell me to stop One Drive, so I tried. Anyway, I deleted my One Drive file/sims 4. I also wanted to move everything to D-disc beacuse I have much more space there. I tried to make a new map there and renamed so Sims would read it. Somewhere I obv did wrong. Whatever happend is maybe irelevant, whats importens is that i have everything saved in back ups. Tray, mods, saves. How do I get the right maps where I can place everything and it reads correctly? Now it Say start new game like its the first time playing, everything is gone. Do I need to repair the game or reinstall it to get the right maps back without one drive? Can I even have it in D? Hope this makes sense somehow. Been crying all night.
