Just for your information, I just had this error with my Traktor Pro:

and I remembered that I have had this before, with SEVERAL NI products actually. Luckily I remembered the solution as well.
You have to disable your FLOPPY drive in the device manager;
Start > Control Panel > System > Device Manager
there you just disable the floppy drivers.
SOLVED!
Hope it helps someone in the future.
