How do I install on a different computer?

I bought and downloaded Amnesia a while back from the Frictional Games website. I recently got a new computer that will run it faster. How do I download it onto that computer?

Have you tried the shelf? I don't know if it works for games that you've purchased through the FG website (I've only used it for the soundtracks), but it's worth a shot.

Congrats on the new computer, by the way. Amnesia made me realize I needed a new computer after my old one died while playing it.

Hah, posted at the same time Darkchef did! Oh well, you get double help.
