Hacking message?

When i was going to start a game and got to the loading bar where it shows the map and stuff, and i was taken back to the lobby and tried to start the game again and yet again i got taken to lobby, but this time when i tried to start i got a message saying "your account has been logged and subjected to ban" or something.

This mean I'm banned or will be banned?

This is just a warning that you might be banned.
I have gotten before and nothing has happend.
If the problem continues try Re-Installing.
Thank me if I helped =)
