Re: Please help. A serious error has occurred while loading Sunset Valley. New Game.

I tried attaching the file you said to attached, not sure if it did.

You could delete the Sims 3 folder in Documents by manually dragging it to the recycle bin; the game would be forced to spawn a new one the next time you tried to launch.  There are plenty of causes of corruption in this folder, although it would be surprising if it was causing you problems before you ever had a chance to play.  Still, one potential issue is that your currentgame folder could be corrupted.  If you click on it and it won't open, that means the game can't open it either, which could cause the "serious error" message.  (Side note: that folder should always be empty when you're not actually in-game, so if you ever do find files in there, you should delete them.)

Trashing your TS3 folder should get rid of a corrupt currentgame folder, but if that's not the problem, there's only one other potential solution I can find:

I think you tried unticking the "read only" box, but there's another fix to try at the bottom of the page, under "still not working?"

@kittymew1234  A guess is the video chip (GTX 1050) may not (probably not) be in the game database and the game is crashing because of this. This is what I used to add my graphics chip to the database - link - Adding a new graphics chip to the Sims 3 database  It is not as hard as it looks but if you never did anything like this before a little help would be nice. I recommend copying the two .sgr files to a safe location THEN editing the files so you can recover if you need to.

Ok so I looked into the adding the graphics chip one, but...it said to go into the Game folder and I checked to do that, my Game folder doesn't even exist! How is this possible? I bought the game, it's my Origin Library...

@kittymew1234  The two files you need to edit are in in the Origin folder. The user files in the documents fold will not be created until you scucessfully start the game the first time. The two files you need to edit are the .sgr files in the Origin game files.

I honestly don't know how else you could try to fix this problem, other than editing the .sgr files as @roberta591 has mentioned.  (I didn't have to do this, and I wouldn't know where to start, either.  At this point, I myself would probably go through the whole process of uninstalling, cleaning the registry with a tool like Piriform's CCleaner (free), and reinstalling from scratch, but editing the .sgr files is certainly worth a shot.  You can probably find them here: C:\Program Files (x86)\Origin Games\The Sims 3\Game\Bin but that will depend on where you told Origin to install TS3.  Regardless, you're looking for a file within an application's folders, not anything in Documents.

Ok so now I have reinstalled the Sims 3, now the error message I'm getting is pretty much the same but instead, it's Sunset Valley World instead...
