OK, those displacement bounds look way too low to me. They're lower than the setting you're using in the material room. They need to be at least as high. Try turning them up to 5 say. If that works, bring them back down to 1 and try that, then try bringing them further down to 0.35 since that's the setting you're using in the material room.
