Black Screen PLEASE HELP (mac)

[h76tr]

So I've played Machinarium once an it worked perfectly.  I beat the game and now I want to play it again but every time I launch the game I get an eternal black screen.  The top bar says "/Macintosh HD/Users/Christian/Desktop/Machinarium.app"   I have OS X  Version 10.8.5 .  I no longer have the folder that goes with the application nor any proof of purchase.  PLEASE HELP

Also I have the Adobe Flash player 11 and in the options on the player when I have the black screen it says "more about Player 10." Is this a problem?  also I downloaded using Humble Bundle

I no longer have the folder that goes with the application...

You need to have the folder that goes with the application; otherwise you will get the black screen.

I suggest you e-mail the Humble Bundle people so that they can send you another link to your key page.
