I just downloaded SMB after watching the great Indie Game: The Movie-documentary, and I played through the first stage until I got to The Hospital.
I quit the game then, and now when I tried to launch the game it just crashes on the first screen which says XBOX LIVE ARCADE. I can't do anything on that screen, the only thing that works is to turn the console off and on again.
1) Deleting the game + savefile
2) Redownloading the game from the Download History page
But the same thing happens when I launch the game.
I tried searching this forum and elsewhere but came up with diddley.
HLEP me plz, The Internet.
