Sims 4 help

@siyanna  Please use this guide to change the location of Documents:

Change only the Personal value (this is Documents) to the default, which is %USERPROFILE%\Documents , as written in the guide.  Then restart your computer and see whether you can play Sims 4.

If the game does work, you can use this guide to create a symbolic link to the location on your external drive where you want the user data:

This should be in a different folder than the game's program files; the two should not be mixed at any time.

If you get the "already running" error again, please try the other suggestions in this guide:
