Help with the game: Art of Murder - The Hunt for the Puppeteer :O?

I’ve started playing this game and I’m really enjoying it so far.
But I get to the part with the slot machine and it doesn’t work.
I can start putting the euros in but then it freezes and I have to exit the game.. :/
Do you know why it’s doing this? Or am I just not playing it right?
I’ve heard of these savegame things? Do they work and where can I get them?
