Don't worry about your English, everything's coming across clearly :)
From the error, it seems like the 'txt' folder isn't in the right spot. If so, that would allow the game to start normally but you would not be able to go any further than the start menu, like you described.
Can you make sure everything's in the folder like in the screenshot?
Can't really think of anything other than that, so I'm really hoping that's all there is to it ><
