well I found another link to download it someone posted but now i can't even use it sadly for some reason the level editor doesn't work because I can't place anything at all next is that i can't even play the already created levels because when ever i try to open up the game a message pops up saying...

Because there is no smbx right now, in the meantime is there anyway to download a different version of the game, if so please let me know, i have been really eager to play this game.
