Reply to Traktor Kontrol S2

I need a confirmation, since NI seems to give a flying f*** in its customers.
I've got the Traktor Kontrol S2, and i have suddenly got problems with it. GLitching and freezing all up. Is this known by other users? And is it a driver problem? I asked the same over at NI, and the other users just told me to buy a Mac. Well if i wanted a Mac I would have bought one. But for now i have a Windows based system Win 7 x64.

Please someone tell me there is a fix, or i can throw the kontroller as long as i can.
