NI-DAQmx Tools error: Unable to load DAQ library from data directory

[kmm]

I have a USB-6009, which I am trying to set up for use in Matlab with NI-DAQmx Tools to do some more nuanced data collection than I had been doing with NI Data Logger. I have downloaded and installed DAQmx Base (2.1) and NI-DAQmx Tools (http://zone.ni.com/devzone/cda/tut/p/id/3005). NI-DAQmx Base List Devices as "NI USB-6009: "Dev1"    (usb6009)". I gave it the alias usb6009 (which may or may not be part of the trouble).

I can collect data using Data Logger, so I think that my device is set up and working correctly. However, when I try functions from within Matlab:

[data, time, initial_time] = AcqNUpdates_UI

or

[data, time, initial_time, timed_out] = AcqNUpdates('Dev1/ai0', -10, 10, 100, 1000, 10)

I receive an error box that says "Unable to load DAQ library from data directory".

DAQ_Demo_Browser does bring up the help for the DAQmx Tools functions, and I have made sure that the ../toolbox/natinst/daq folder is in the path.

Any suggestions would be appreciated.

Thanks
Kevin

Replying to my own post. I apparently had not (properly) installed NI-DAQmx 8.3.

The KB article at http://digital.ni.com/public.nsf/websearch/1448A8AC665EE0EA8625703F004A4410?OpenDocument was also helpful in sorting my subsequent 200220 error.
