Akai MPD32 & Traktor Scratch Pro - Midi Mapping

Hello.
I also have a MPD32 unit for which I have updated the firmware to version 1.3. I'm running Windows XP and my PC recongnizes the MPD32 as 'USB Audio Device' which is normal from what I gathered on the web. Also, when I run 'Vyzex MPD32', it recognizes the pads and dials that I press.

Now, my problem is this : In Traktor Scratch Pro, under the 'Midi Setup' tab, I see many Ports, including my MPD32's (I think) called :
USB Audio Device (Emulated)
USB Audio Device (2) (Emulated)
USB Audio Device (3) (Emulated)
I have tried Midi mapping with each one and also with all three highlighted. Nothing works!
For example, I have clicked on 'Add' - 'Load' - 'Load Selected'
Channel is 'Focus'
Type is 'Trigger'
Then, when I click on 'Learn' and I press the Akai MPD32 pads, nothing happens. Please tell my what I'm doing wrong. This has to be software related because like I said, Vyzex recognizes every key that I press.
Does the Akai have to be set to a certain status/menu ?
Please help.
Thanks.

PS : And also, if anyone has a .TSI file for Traktor Scratch Pro, would you please send it to me. I would greatly appreciate it!
