Unfortunately there was a tiny problem with the 0.10.0 binary demos archive; an out of date .material file will cause you to get an error in the ‘Terrain’ demo about ‘Examples\TextureEffect4’ being missing.
I’m updating the archive now, but for those who have already downloaded it, you can grab the updated material file. Just save this in the ‘media’ subfolder (overwriting the one that’s there). Apologies for the error.
