Aerodrums and Aered forums

Trying to re-install now, thanks for the help

I'm having the problem with all kits, I can't see or hear any drums at all. I just get a blank screen with the menu button. That's why I assumed I needed to "Place all drums".

I've se tup my markers and selected a kit but whenever I select "Place All Drums" the program crashes , I'm running it on a late 2012 Macbook Pro with a 2.5 Ghz i5 and 4 GB of ram.
