I have used Sims 3 Night Life before playing sims 3. I have 4 other expansion packs that I can see downloaded,but Night Life is not there. In Origin it says it is purchased and to check my library but when I go to my library it does not show up.

@Kaklemm When you go into your Origin library and click on the TS3 icon, scroll down and select More > Expansion Packs. What does it say under Night Life? My packs say Download or Play, depending on whether I have them installed or not. If yours says Buy Now or Details, try clearing Origin's cache. If that doesn't work, uninstall and reinstall Origin only ("the hard way"); this won't affect your installed games.

If it still doesn't show up, you'll need to contact EA customer support to ask if there's a problem with your code. Sometimes EA deactivates a code; it can be a mistake, or it can be that the code itself was bad. But there's no way to get that information from Origin—only a support rep can tell you.
