App keeps uninstalling

Since the last update a few days ago the app works untill I play the Sims 4 I save & quit game & log out like normal but then when I go to use it again it is completely missing from my game & my games are still there & when I go to website to reinstall I have the option to launch or repair & I check repair now, still does the same thing & this has happened several times now. Also new problem looks like the app updated again because now it is blue instead of orange & now I get a message that my EA pro membership has ended so games have been removed (yes I already knew this especially since it way May of last year) But you also took away my special promo games that I earned when you use to have a game for free download once a month (without EA play membership) as well as other games I have purchased thru all the years! including content I do not see listed on the app anymore! It was already on my computer & now it has been deleted by your app even though I purchased it literally years ago all with out my consent on my personal property all my Sims 3 store content has been erased too & your Sims 3 website is no longer up & running to even download it! I want all my games & content back that I purchased all those years ago. Also the add on for Sims Medieval called Pirates & Nobles bonus content I can't even get back as that was a code you had to type in when purchased the game so I am up set about this too & add on game isn't even showing on your app to reinstall it either, btw this is one of the games you are trying to get me to buy again as well as some games that I literally bought when I had EA pro membership. And while I'm at it Why does Sims 4 content still seem so empty & lacking, I hardly have any item in my game even though I own all the expansion & stuff packs as well as all the kits! Why am I missing items! It's not my computer as I have no problem on other platforms where I am also  a playtester & a lot of their requirements are much more demanding than the Sims 4. As well as other programs because I like to dabble with recolors & making my own meshes from time to time, which again require more specs & space than the Sims 4 yet they run just fine. Please fix this issue as soon as possible I want my games & my content back, all of it!
