You are running version 19 of the game.
Upgrade to version 20 with the new Launcher which you can download at the main page.
Just noticed that.
The new RTB requires fixes from v20.
Badspot seriously needs to make a "mandatory" v20 automatic update (v19 automacly gets to v20, instead of downloading it again), so stuff like this won't happen neither to the current players, neither to the old who don't visit the website often to get new updates and stuff.
