@XHiGeminiX For the original issue, the cause is that Sims 4 will always look for the user folder in Documents > Electronic Arts, and if no Sims 4 folder exists there, it'll create a new one with no content. You can't simply move your saves and mods to D and expect the game to find them there. The ways around this are to move all of Documents to D (only if D is also an internal drive; don't move the Documents directory to an external device) or to create a symbolic link pointing the game to the user folder on D. Both options are covered here:
For the second issue, it sounds like your packs were reinstalled into the wrong folder. Please run a couple of searches for these packs, starting with EP01 , which is the folder for Get to Work. Open a File Explorer window, click This PC in the left panel, and enter EP01 in the search field in the upper-right corner. Wait for the search to finish, then make sure the full file path is showing under each result. If it's not, expand the window sideways as necessary. Take a screenshot using Windows key-shift-S and attach it to a reply here.
Please repeat the process for one or two more packs.
