Re: Unable to connect to EA servers to activate Sims 4.
@NastyaVicodin
1. Are you sure you are on the same account what you create when registering the game?
Run Origin as Administrator. ( Right click-Origin icon "run as Administrator")
Go to the Origin/library and check if your game is there and check it has the mark "installed".
If it is there - right-click on TS4 - option "repair game"
2. Uninstall Origin using Revo program - free version it will be clean your computer of all traces of Origin

and download again
http://origin.com/download
3. If it still will not work probably your antivirus program or Windows Defender is blocking it.
In this case, you can add the game to exception

4. Try to launch the game in windowed mode

5. There is also a possibility that some of your programs running in the background are blocking it.
If you have it - disable the Rivatuner overlay. If you have Nahimic program - uninstall it.
