Hi leo_kasper0069,
That message appears to relate to a ban, I'm afraid. If that is the case, you'll need to try appealing to EA's Terms of Service team, as they're the only people who can potentially revoke a ban. If you wanted to try, the guide below should explain the process and a webform to begin the appeal. Alternatively, you can scan the QR code in the message you're receiving.

This is inaccurate as its an issue within the game. It has nothing to do with the account as other systems besides PC work.
