Reply to Upgrade package from Traktor Pro to Scratch - anyone?

So i bought the S4 upgrade package to add scratch functionality to my existing traktor pro license (NI customer service told me this crossgrade would work, and even the packaging says "works with traktor pro 2 + NI soundcard/certified mixer). i also bought a TA6 for timecode-input.

got my tt's and everything works like a charm except for the scratch-timecode-license-thingy.
I installed the traktor version, that came with the upgrade package (2.1.1) but traktor still starts as "Traktor Pro 2", no scratch functionality...

i tried to upgrade in the service center by clicking the "Upgrade" button on my existing Traktor license and typed in the serial of the scratch upgrade package. The service-center said it was an invalid serial.

so far anyone who did this crossgrade successfully?

please help

(i alredy got a ticked at NI customer service running, but i don't have a reply for a week now...)
