Cannot find my sims games since one of the updates on Origin.

Alright so, I wasn't having problems with downloading my sims games in the past but ever since one of the updates ( I cannot remember ) all of my expansion packs were gone. The base game for Sims 3 and Sims 4 were still there but everything else was gone.

My old computer broke but before that, when I did go onto Origin/My Games, there was something like a link from Origin saying that my games were moved and I had to click on the link ( I guess ) to find all of my expansion packs that had moved and I could download without any problems. But now that I have a new computer, that doesn't show up anymore and I'm not able to find my Sims 3 expansion packs.
