From what I can piece together, that's an error that happens when the game's anti-cheating tool flags you as a cheater (rightly or wrongly, most people get flagged wrongly). For a time (nobody knows for how long), your IP will be flagged. If you try to enter tournaments, you'll get that error. You can solve this by reinstalling (though at least 1 player is currently locked out of tournaments even despite reinstalling).

However, as your IP is flagged for the foreseeable future, you might encounter it again. As far as I can tell, this error will happen if you get a crash or timeout while mid-tournament.
