[split] misc game not running, crash on startup

[Shade080]

Im having trouble with a part of my graphics (note that im using the demo). i turn on the game it runs smoothly, except everything looks very off. theres no real textures. everything is black. but rugs and rocks are bright white (i assume there rocks i can't tell). so i exit and look into my documents and check the hpl i see an error that says: ERROR: Failed to compile GLSL shader 'C:/Program Files/Amnesia - The Dark Descent/redist/core/shaders/deferred_gbuffer_skybox_frag.glsl'!
Shader code: i either see that or ATTENTION: System does not support const arrays in glsl! please help. i using windows vista if that matters
