@clairecoffee Screenshots of the errors would be great. I'm not sure why tech support couldn't or wouldn't add your packs back into your account; it shouldn't work like that.

My Library But nothing happens when I try to Upgrade or Download
@clairecoffee I'm so sorry, I somehow missed your replies. Do you still need help with Sims 3? If so, you have two options. One is to try again to upgrade your version of Sims 3 to the Access version, the one that includes Late Night and HELS. If you can't click Upgrade directly, clearing Origin's cache and launching Sims 3 once usually triggers the offer to upgrade again.
You could also try removing the game from Access and re-adding it. Open your Origin game library, right-click on the Sims 3 icon, select Uninstall, and choose "Revert game edition." If you don't see this particular option, let me know.
The other option is to skip the Access content entirely. In that case, you wouldn't be able to play your old saves, but your other packs should stay installed going forward.
