Hi, just joined to say that I'm also experiencing the same thing as that other lad (crash on startup).
Any ideas why that might have happened.
What I did is download muppen as OP said, copy pasted the config file posted by kil3r previously (since I wanted to have a similar config to his) and ran the emulator.
It instantly crashes when I press any button on my keyboard.
I don't use an anti virus and everything is up to date regarding GFX cards/firmware and all that jazz.
