Spline IK Problems

I’ve posted this query in many Blender Forums, including this one, about the Spline IK constraint and have gotten absolutely no response for my problem. I’m not even sure if it is a bug or just the way it functions. But, whenever I try to use the Spline IK constraint, the curve, bones ( that the constraint is used on) and mesh all disappear with the exception of the bone-hooks. I’ve been looking for tutorials and vids on how to use the Spline IK, but they seem to be only one. That one I have used and the above problem always occurs. This a bug? Is there tutorials how to use the Spline IK?
