Sims 3 expansion won't download

8 days ago, I was forced-prompted to switch from Origin to EA  app. The initial switch transferred games and files over just fine, but I had an issue with the sims 3 store content not staying installed, which corrupted my save files. It's fine...whatever. 674 hours down the drain... no problem. Im over it (I should have backed them up...I guess.) MOVING ON! So in order to fix that problem, I did what EA help suggested. Uninstall EVERYTHING, (sims 3 game, all expansions, content, and files) including their EA app, and start with fresh new installs, all updated and pretty (even though they already were...). All reinstalled fine except for 3 specific expansion packs that will not download. They get stuck on "Preparing" and never move forward. (pic included) University Life, Island Paradise, and Into the Future. I have uninstalled and reinstalled everything more than a dozen times at this point (EA has continued to give me this same advise repeatedly even though it isn't working!) But still these same 3 expansions will not download. If I leave it on "Preparing" long enough, I will get an error message that states something to the effect of" "something went wrong, please wait and try again" (pic included). Im frustrated to the max with the extremely limited and horribly slow EA email help system. They haven't helped at all, and I'm sure they don't care. I tried to go back to Origin earlier this morning, but I just receive the same forced prompt to switch over, and cant get around it. At this point I just want to know how I can take my games OFF the EA platform and download them directly. I have spent thousands of dollars in this game over the past 10 years and hundreds upon hundreds of hours of my time. I just want to play my old-* game in peace! Can anyone offer any suggestions at all on how I might fix these issues with the downloads, or how I can get around EA all together. Thank you.
