he means if you bought it. Since you didnt do this anways so hopefully they can de-activate ur not so legal version.. the top secret "free" pro edition

BTW someone made a comment where you need to upgrade to 6.5 in order to make multiplayer games, because the prior versions are bugged. Well i'm using 6.4 and its fine, and as I understand it when a new engine upgrade comes out such as when 6.4 came out, it has bugs until made final (put on the download page). Last time i check it was still in trials, then again i might be out of date lol.
