Can't play Penumbra Overture

[linkwolfy]

So i bought Penumbra Overture yesterday, downloaded it and attempted to play it.
It would say "Preparing Penumbra Overture" And i would have to wait for several minutes before it would finish, and i would get a "Not Responding" screen, then that would go away and it would say that Penumbra was unavailable. So i tried several times after, then it game me an installation link, something like OpenAl or something like that, i can't remember, so i installed it. It now starts up, and goes to the menu, where i can start the game, watch the opening video, but as soon as we finish loading after the video. The screen remains black.
Then a "Not Responding" thing will pop up, and I say wait until it responds, and it never does. So i exit it, and try again and try again, only once it made it far enough to start the music for the scene and start to show the picture. Then froze.
What can i do to fix this?? I'm using one of these: [url]http://www.amazon.com/Acer-Aspire-One-D2...+one+d255e[/url]

And it has an Intell Atom N455 (1.66GHz, 512KB Cache) And i was told it could play and handle it.
Is it something i need to download, or update or what?
Thank you for any help you give, I would REALLY like to play it.
