Hi Markus,
I apologize for the inconvenience! Due to the enormous number of spam email that we were receiving, we had to change the email address to instrument.drivers@ni.com ("drivers" instead of "driver"). Most of our pages on IDNet (Instrument Driver Network) list this new email address at the bottom of the page.
Please resend your email using this new email address.
Best Regards,
Vesna Jadric
