The Sims 2 - Ultimate Collection 2017?

So when the Sims 2 Ultimate Collection first came out, i downloaded it. It took pretty much a whole day to download everything. i have the files on my computer, so when i tried to play it afterwards, i found it on my files. But it wouldn't work. TS2 Ultimate Collection doesn't appear on my origin account, even though that's where i got it from, but it appears on my compiter. What should i do?
