@puzzlezaddict Got it to work with those two packs, but after installing pets, I'm getting the error again with the Supernatural thumbnail.
@HannahLynn98 This is still strange; it worked fine the last time I did a test reinstall. Granted, that's been a few months. Just to see, please try launching by double-clicking on the base game icon, and Pets if that doesn't work.
If you still get an unknown error, maybe none of the correct folders are copying over? You can look for them easily enough. Inside Applications\TS3, right-click on the Sims 3 base game icon and select Show Package Contents. From there, the path is:
Contents > Resources > AddOns > Supernatural [show package contents] > Contents > Resources > transgaming > c_drive > Program Files > Electronic Arts
Inside Electronic Arts, what folders do you see, and are they aliases or full folders? (If a folder has a little arrow in the lower left corner, it's an alias.) Since Supernatural is newer than Pets, there should be a Pets alias inside, created the first time you tried to launch the game (via the Supernatural icon) after installing it. Please list everything that's there. If there's nothing Pets-related, you can try copying over its folder into Supernatural, as in the unknown error video I linked. If there is an alias for Pets, right-cllick on it and select Move to Trash, then copy over the folder.
The other three folders were all alias' (base game, HeLS, & Pets). I deleted the alias Pets folder and copied over the full folder from Pets' 'Show Package Contents'. It's still giving me the error.
I apologize for this being messy.
@HannahLynn98 You're not being too messy, it's just strange to me that the game is being so stubborn, especially with packs that are supposed to be easier to handle. If all the folders are in place, and you have an icon for each pack in Applications, then I honestly don't know why the game isn't working. I take it bypassing the launcher didn't help? On machines without much RAM installed, the unknown error can be due to the launcher reaching for more memory than is available, but that shouldn't be the case for you.
The only other thing I can think of at the moment is installing a newer pack than Supernatural, to see if that helps. Maybe if a different pack is launching the game, whatever problem you're seeing now will no longer be in the picture.
Tried that with IP - still didn't work. I think I'm just gonna give up on it for now and just stick with TS4.
Thank you so much for trying to help though!
