Once again, thank you for your replies and willingness to help people here. I have read a lot of posts where you have gotten people's games working through your tips and knowledge. So thank you for your efforts.
According to EA's twitter, they are telling sims 3 and sims 4 players to uninstall and reinstall the EA APP. That there is a glitch where sims 3 and sims 4 players both are not able to see their owned packs or download them. That the sims 3 and 4 aren't even appearing in their libraries.
They said they put out an update to the app, but some people can't get the update to work. That we must uninstall and reinstall the app.
After doing that just now, my sims 4 is actually showing up in my library and my sims 3 is actually showing that I own all the expansion and stuff packs. So yay sims team for that.
The launcher is letting me sign in as well finally. I can now load my game with all expansion packs. I just can't get my store items or saves to work.
The sims 3 website still is not working for me. I tried chrome, firefox, Microsoft edge, and Internet explorer on compatibility mode. I tried my mom's account on her pc. My grandmother tried it on her pc at her place. They can't get it to work either. My aunt it let her get to purchase history but when she clicked download, it says she didn't own the items.
Edge let me log in just now, but when I hit purchase history.... it says bad gateway. If I refresh a few times, I get logged out and can't log back in. I have to delete the cache and the cookies and try again. I can log in at EA's site ( EA.com ) then go to the sims 3 page, I am logged in. I hit purchase history and get logged out instantly. It just keeps repeating.
According to the EA sims 3 store forum, at lot of people are having issues logging in and have for months. The browser doesn't seem to matter. It is hit or miss. Sometimes it says under maintenance. Other times It just keeps asking people to log in time after time or giving a bad gateway when they hit purchase history. Other times it tells people they can't download their items and that they don't own them.
EA Cade has posted in several of the threads that they are aware of the log in issues.
My brother's discord community has been posting all their issues too. Many have finally got their games to load with the newest EA APP update ( uninstalling and reinstalling ). Sadly they are like me and just can't get the sims 3 store or purchase history to work. At least sim gurus have said they are aware people are having issues. So maybe that means something will finally get fixed.
Again, thanks for spending your time trying to help people. I have MS and my doctors told me I needed to de- stress. That I needed to play some games and relax. Stress will kill me faster. Since December and the EA APP - it has been anything but relaxing.
