Amnesia: The Dark Descent - Crashes on Startup

[Prophet5]

I'm guessing that's the Celeron dual core T1500 and not the Core Solo T1500. It's a little under powered for Amnesia, but shouldn't stop it from running. I'm still sure given the "double free" error that it's memory related. How much memory is the system taking up? Remember you are down to 1.7Gig without system resources due to the X3100. I run KDE here and it is taking 1Gig, although 990meg is in disk cache. Actual processes are taking next to nothing.
