Looks like terrain shader didn't compile. And this gpu is quite good I think.
We need ogre.log attached (like always) from one track that has this.
This looks even more strange since the terrain is ok close to camera, but turns 
black after some distance.

I doubt its composite map (not so close), could it be some fog params error ?

please post an ogre.log where you actually loaded the track. (the one you 
posted is just from entering the menu and then quitting)

Anyway, it's a new log, where I passed the full circle.

This line looks strange for me:
 * Supported Shader Profiles: arbfp1 arbvp1 glsl gp4gp gpu_gp nvgp4 ps_1_1 ps_1_2 ps_1_3 ps_1_4
For comparison, mine is (gtx 560 Ti):
* Supported Shader Profiles: arbfp1 arbvp1 fp20 fp30 fp40 glsl gp4fp gp4gp 
gp4vp gpu_fp gpu_gp gpu_vp nvgp4 vp30 vp40

So clearly you haven't the needed shader models supported on your card.
But there aren't any exceptions from terrain shader compiling, odd, and some 
tracks work, hmm maybe because of less layers used.

can you run the ogre terrain demo (OgreSampleBrowser) ?

So, I run that test. Errors appeared in "Particle essects (GPU)" (it say, my 
video card does not support vertex buffers). Also, I noticed, that test 
"Terrain" have bug (feature?), like in stuntrally: terrain turns black after 
some distance..

PS: test "Texture array" drops segmentation fault
PPS: my english is awesome %)
