I was forced to download the EA app about a week ago and have not been able to play the sims ever since (exteremely sad).   it says i have to uninstall my steam version of the game, but i know that whenever i don't launch with steam and only use origin, i lose all the expansion packs i bought through steam.  when steam was released, i purchased and installed the base game and a few expansion packs on it.  if i launch the game without having steam.  i don't want to play the game without all the things i purchased because 1. it means all the money i spent is thrown away and unused and 2. none of my gameplay will function anymore since my saves heavily revolve around the expansions purchased through steam.  i have purchased almost $200 worth of expansion packs through steam and i feel like its wrong to not be able to use something I've invested so much money into.  this game is very important to me, i play it every day as its the only thing i have that allows me to escape from the stress i face daily.  I've tried everything i can think of to get it to work, so i came here to beg for some help or at least some guidence.  please I'm desperate lol
