Product Design Suite Ultimate not in Autodesk account?

I just looked, and I’m running an old version of Inventor 2016. I got it as part of PDSU 2016. When I go to my Autodesk account, prior versions of Inventor are listed there, but nothing for Product Design Suite (under either Inventor or anything else) therefore I can’t download updates (I think?)

Anyone else have this problem or know how to solve it? The software works great otherwise.
