The Sims Medieval won't download, please help

I bought The Sims Medieval recently, and I've been trying to install it on the EA app for the last two days. It starts downloading normally, but everytime the installation reaches 100%, it restarts, without any messages. 

I searched the internet far and wide for a solution, reinstalled the app, updated my Windows, cleared the app's catche, closed all background programs, deleted all game files, but nothing works. I tried talking to the EA Help chat, but it doesn't work, every time when I fill out the questionaire it redirects me back to the starting page.

Please, does anyone have any idea how to fix it? I don't know what to do anymore.
