I had changed my in-game screen settings so that they were not fullscreen. It worked out well, until I closed out of my game. When I went to play it again, it only loaded the launcher and the sounds, the screen was still black. So, I decided to come on here and follow the trouble shooting steps.
However, I knew where I went wrong, so all I had to do was open up the options.ini file in both my Sims 3_Backup folder and my new Sims 3 folder, find the fullscreen setting, and change the 0 to 1 (So that it matched the default setting.)
It fixed my game, without making me have to copy and paste all of those files.
I did everything you said, and the game will actually launch, but when I try to open a saved game, the checkmark to load it is greyed out, and the town is missing - even though I put my Installed Worlds folder back. I'm so upset because I can't open any of my games because the towns are apparently not there.
Also, I have all of the expansions, and I know the load screen changes with each, but it's just the base game load screen; how do I put my expansions back? I'm 99% sure that would fix my problem.
i do not know where the options.ini file is in my backuo folder it is not there
@VildaCullen Crinrict's guide refers to your Sims 3 game folder and its contents, not your program files. The game folder can be found in Documents\Electronic Arts, and removing it from there (or renaming it, as described) will force the game to generate a clean folder, hopefully without whatever corruption is causing the problem.
It might be easier if you made your own post describing the issues you're having with your game. That way, you'll get help that's more specific to the problems you're seeing. A clean game folder is a good place to start, though.
So this seems to have solved my problem - so thank you.
The issue I have now, is content in my game, such as tables, lamps, etc. are being replaced. It looks like content from the expansion packs.
Do I need to reinstall something? Including the expansion packs, and if so, how?
Do I need to reinstall any extra mod content (they are all replaced back into the folders, but I am curious if I have to 'run' the Sims Custom Content gain to install it. )
@lavagoddesss When you go into Buy mode, there's a button that lets you sort items by the pack they came with. Are all your packs listed? If not, the launcher may be unchecking packs from the installed content tab, or it may be ignoring your selection. The solution is simply to restart your computer, uncheck all the tabs, and then recheck them. This is definitely tedious, but the launcher is finicky like that.
If your custom content is in your game folder (from your comment, I'm not sure what steps you've taken up to this point), just make sure to delete your cache files. They should be cleared regularly anyway, and every time you add or remove content from your game folder. For reference, they are:
If this doesn't help, or I'm misunderstanding the nature of the problem, please let me know, and I'll try to help.
