Reply to Hello. not recognizing s4

Hello, guys

I am using Traktor pro 2 2.6
I just changed my labtop. it is PC and pretty new. all the specs are no problem to run traktor pro 2.
I try to connect S4 but it cant recognize it.
I cant find anything from setup wizard as well.
when i load previous setup it shows S4 on the side but on the bottom it keep say i need to connect device.

So, what I have done so far is un and re-installed traktor pro2
Checked, USB code + Cable

Iam not sure why it is happening.
MF is working but S4 is not.

Thank you for advance.
