Ahhh, now I understand! When first trying the game, you switched to the rogue, which has a tutorial section, but it's hard to understand if you haven't first played the knight.
That's why I changed it so that the rogue unlocks later on in the game. You must have redownloaded the later version of the game, but your savegame still contained the rogue run, but then it got locked.
Hope the game is now a bit more understandable for you, sorry for the confusion! :)
