Add native game to Steam without buying again?

As far as i know, there isn't. However, if you can tell us a little bit about your system and post any hpl.log from ~/.frictionalgames/Amnesia/Main, we're likely to tell you why it wouldn't run on your system.

I posted my initial complaints here http://www.frictionalgames.com/forum/thread-17982.html

Haven't gotten a reply in a while. I figure the tech guys are busy with things, but it's infuriating to have bought a faulty product, and I had thought the steam-virtualbox idea would be a better solution.
