Reply to X Fader problems

So I bought a VCI100 SE off someone on the community s and downloaded the most recent mapping for Traktor 2. I installed the mapping and my crossfader isn't working correctly. It is either all the way left, in the middle, or to the right. I don't know if this is a mapping problem or the actual controller's problem which would lead me to start a paypal case for a faulty product.

Anyways...if it IS the mapping, i'm new to traktor and don't know how to map the crossfader properly. Someone help?

thanks!
