When I tried to open it on origin the "play" button was pale and not letting me play. I clicked it a bunch, got mad, and angrily searched why it wasn't working. By the time I got myself into such a bad mood I looked at my taskbar and realized that the sims launcher was running

This same problem happened to me, but i completely exited Origin and logged out. I didn't think it would change anything, but when i was logged out i tried to open the Sims, obviously sense i was logged out it didn't work, but it opened a page for me to sign in again, or relogged the one i was using. I signed in and the Sims was working again! This problem also happened for me in PVS Garden Warfare, and it worked as well!!! I hope this helps lol idk

Hi! I had this same problem too... It was so annoying.. but I didn't want to uninstall Sims 3 as a whole because i didn't want to lose my data. I tried uninstalling origin and reinstalling.. nothing. what you need to do is go to Task Manager and first look in Applications, and if it's open, close it out. If it isn't open, and you still can't play, go into PROCESSES and look for a Sims3Launcher and close it out! this worked for me and now i can play.
