I recently made an origin account and bought The Sims 3 starter pack. I followed the steps and downloaded and installed it. Right when I tried to play it, a message keeps popping up saying Unknown error code. I restarted my computer and tried again and even tried signing out of my origin account. The same message kept popping up. I googled the code and other people have had the same problem as me, so I followed their steps in manually uninstalling the game and uninstalling origin. After this long process and reinstalling both the game and origin, I tried the game again. It went farther this time because it actually made it to the Sims 3 launch screen but wouldn't actually let me play it. I tried restarting my computer again and opened the game again to the same Unknown error message. I don't know where to go from here. I'm upset I can't play a game I paid 20$ for and would appreciate any help. Also forgot to mention I have a macbook pro that I also recently updated too, if that's any help.
