Re: Infinite loading screen
@flownty Thanks for the dxdiag, which shows, among other things, that your C drive is critically low on free space. 7 GB free is barely enough for Windows to maneuver properly, and this alone could be the source of the problem. So please try to clear another 15-20 GB, to eliminate this as a potential problem if nothing else.
Once you've done that, restart your computer and try again to play. If the game won't load, and you don't need to wait more than about a minute if you're testing with a new save (go ahead and kill it in the Task Manager), please update your graphics driver. The one you currently have installed is relatively new, but the Sims 4 errors in your dxdiag could be related to the driver. Here's the newest one from Nvidia:

Run the installer as an admin: right-click the download and select "Run as administrator." Choose the Custom (not Express) install method, and check the box to perform a clean install. Restart afterwards and before trying to play.
