Let's get the obvious questions out of the way that I've seen asked on similar questions:
Are they installed: Yes.
Do they show up in the Launcher: Usually, reloading the game launcher fixes that if they don't.
Are you clicking them: Yes. But they don't stay on when I play the game/close the launcher to check. They uncheck themselves. All of them.
This is a semi-regular problem. Eventually, they do load properly. But a permanent solution would be nice, please.
@Wings12312 I'm guessing from your description that you play Sims 3. For the packs getting unchecked, try clearing the cache for Internet Explorer. It stores some launcher data, including the packs you've selected, and that data can get corrupted.
The packs not showing in the launcher at all is usually an issue with Origin's cache. Here's how to clear it:
@Wings12312 Do you run a cleaner app on your computer, or anything else that might be messing with Explorer's cache? Does it make a difference if you put Origin in offline mode before launching Sims 3?
