@WitchLilith69 Please go into the game's program files, which are located here by default:
Program Files (x86)\Steam\steamapps\common\The Sims 4
Look for these folders, which correspond to your missing packs:
EP09
GP01
GP05
FP01
If the folders are there, please delete them and restart your computer, then repair the game: open your Steam library, right-click the Sims 4 entry, and select Properties > Local files > Verify integrity of the game files. Then try again to download those packs. If the folders aren't present, repair and restart your computer, then see if you can download them.
If you can't find the folders, please search your computer for them and let me know if you find other copies. Open a File Explorer window, click This PC in the left panel, and enter the pack label in the search field in the upper-right corner. You'll see one of each inside a Delta folder within the game's program files too, but that's not relevant: it's just patch data, not data from the packs themselves.
If you find a copy of any of these folders anywhere else on your computer, please let me know, and also list the full file path to the pack(s). You can see it under the folder name in the search results, or you can select a result and click the Open file location menu button, which will jump you to its location.
