@HappyElk2 I've moved your post to the Sims 3 section.
I'm not sure whether the mods were saved in Notepad or not; that would make them unusable. But it's easy enough to delete them and download fresh copies. Once you've unzipped them and placed them in Mods\Packages, be sure to delete the five cache files in your game folder as well. For reference, they are:
- CASPartCache.package
- compositorCache.package
- scriptCache.package
- simCompositorCache.package
- socialCache.package
If you launch the game and still don't see the mods listed at the Main Menu, quit and then check the last modified date on deviceconfig, again in your game folder in Documents. Let me know whether the time stamp is current, i.e. it corresponds to the most recent time you launched the game.
Also, it doesn't matter that Windows has associated the mods with Notepad. As long as you don't open them again, TS3 will be able to read them just fine.
