Reply to annoying problem with the s4

So here's the deal. I started my laptop and launched tp2 and plugged the s4 in. tp2 couldnt recognize the controller. I tried to solve it for a while and then decided to install the latest update for traktor pro s4. it started working again. But now every time i turn off my computer and start it again i have to go through the same process every time because I can't figure why the software dont recognize the s4. any advice? audio runs thru s4 but it just don't control the software.

a little help for the newbie would be appreciated!
