Error -1074001919 occurred at Read Spectra.vi using HR2000

Hello!

I'm using LabVIEW 2011 (32-bit) on a Windows 7 computer. I downloaded the Ocean Optics 2000 4000 driver and installed the driver as described in the Ocean Optics 2000 4000 Instrument Driver Readme.
So Shawn, I think I use the Driver Revision 1.3.2  (Original Release Date: 11/12/2009 , Current Revision Date: 03/15/2013).

I installed the driver for LabVIEW 2010 ( http://sine.ni.com/apps/utf8/niid_web_display.download_page?p_id_guid=7833BD4A31DA1274E04400144FB7D21D) because obviously there exists no driver esspecially for LabVIEW 2011.
Is this the correct way to do it, or should I install the driver version for LabVIEW 2012?

When I use my HR2000 sectrometer I struggle with the OceanOptics20004000LogSpectrum.vi and I get the following error message (also attached).

Error -1074001919 occurred at Read Spectra.vi
Possible reason(s):
Instrument not synchronized properly. Power cycle the instrument.

When I unplug the device, plug it in again and click on continue nothing happens. The VI can't read the spectrum.
An Excel file is produced, but only contains the header (also attached).

The strange thing is, that the example file AquireContinuousWaveform.vi works and I can see the spectrum.

Do you have any idea how to fix this? Do you think it's a problem with the driver?

Thanks for any help!
