Everything black at the first level?

[Ciradis]

Uh...
So yeah. My games kinda all black except for the snow, my guys helmet, a weird looking white light, and my guys breath.

Im running an AMD 64 Dual Core Processor 5000+ at 2.61GHz, a Nvidia GTX matrix 260, and 2GB of RAM. I've also purchased Cryostasis through the steam store, and the exact error I get from the games error logs (that seems to relate to this issue) is: Error opening file: data\textures\

Little help please, guys? <3
