Ocean Optics USB2000+ no registration in LabView

Hello,

I'm student and just starting with LabView from the basics. I'm using the Ocean Optics USB2000+ spectrometer with

1. OmniDrivers from the Ocean-Optics website
2. drivers (offered by LabView itself)
3. LabView 2013 (32-bit)

My problem is that I can registrate the spectrometer in the NI MAX, but not in LabView. I'm using the wrapper vi's to test it. For example wrapper_openAllspectrometer...

I searched for solutions in this forum but didn't find anything. Sry if it's a really simple question.

Thanks for help, Alex.
