I know how you feel atm . I was playing Marble Blast Gold FULL Version, some years ago, then I unfortunately lost it, I don't know how.. and I was looking for it on net until I found DEMO version I am not sure if I can help you with JJ2, but try to download game again (I recommend you to play in 1.20 because I can't save game in 1.23.. I press Save Game, and choose 1. then when I try to go on Load Game, I see only Empty Empty etc).
