@hudloes When you say you tried to get Origin to repair the game, did the repair actually go through? Even if you think it did, it's worth clearing Origin's cache, to refresh its data, and then repairing again.

If that doesn't help, please create a new admin Windows account on your computer and try playing in that. Make it a local account, as in, don't sign into Microsoft, and don't sync with any other services you normally use. You'll be able to sign into your existing Origin account and shouldn't need to redownload anything, but your saves and other content won't be available.
When you do this, please run Origin as an admin: right-click on the desktop icon or Origin.exe itself and select "Run as administrator." Do the same with TS4_x64.exe once Origin is open.
