Unable to launch Amnesia: The Dark Descent

[Cdub]

I purchased Amnesia: The Dark Descent from steam. The option to play the game or "Run Settings Launcher" is given upon attempting to launch the game, however, the game simply doesn't launch. No screens appear, literally nothing occurs. iv re installed the game, verified the cache files, tried renaming the files hoping the game would remake them, restarted my computer, restarted steam, almost everything. What else can i do?

Im running on windows XP, 32 bit.
im not entirely sure of my other specs but my computer handles most games with ease.
