I did get the AE update (although, I thought that I had it set to not update as I was in a playthrough at that time), and had purchased the Creation Club package as well.
Steam gave me the update anyway so, I lost the game (it wouldn't even make it to the title screen) and the playthrough. It took a clean install for the game to work again.
As soon as I started the game, it started the download and I received all 148 files, whether I wanted them or not. (Thank goodness for Darkfox127's Creation Club content picker tool).
Such is the randomness of my little piece of the universe. Now, back to the game.
