Can't Use Vampires Pack?

Product: The Sims 4
Platform:PC
I want to talk about something you don't mention above: Downloading Packs
How accessible is the current experience? Annoying, but OK
Summarize what in the product is difficult to use. I can't use the game pack I bought.
How is this making it more difficult? This should be obvious.
How can we reproduce this experience? N/A

‌

So I bought the Vampires Pack and it is saying I need to download to use. I have looked everywhere on my Sims 4 game and my Origin. I can't figure out how to do this. Help?

I moved your post to the Sims 4 board.

@kalmiasims  Close the game and restart Origin. New packs should automatically download and install if you activated (or bought) the pack through Origin.

That's the problem, though: I did that. It didn't download. I can't make any vampire sims or use the stuff that came with the pack.

You mean "Show Game Details"? I went there to try that and there is no download button from what I can see. Just a Details button and Purchase As Gift button.

It has recently happened to several players.
Uninstall Origin manually. Download the new version
After installing, run Origin as the  Administrator

I'm sorry for mistake. English is not my native language
