Status Code: -200479 During First Example

[GoogleCodeExporter]

I'm running the first example to troubleshoot why my more complex 
AnalogOutputTask isn't running correctly. Here's the example:

from nidaqmx import AnalogOutputTask
import numpy as np

data = 9.95*np.sin(np.arange(1000, dtype=np.float64)*2*np.pi/1000)
task = AnalogOutputTask()
task.create_voltage_channel('Dev1/ao2', min_val=-10.0, max_val=10.0)
task.configure_timing_sample_clock(rate = 1000.0)
task.write(data)
task.start()
raw_input('Generating voltage continuously. Press Enter to interrupt..')
task.stop()
del task

What steps will reproduce the problem?
1. Running the first example in IPython.

What is the expected output? What do you see instead?
I would expect the AnalogOutputTask to produce a sine wave.

What version of the product are you using? On what operating system?

NidaqMX 9.8 and PyLibNidaqMX 0.2.0 (I think)

Please provide any additional information below.
Any help in understanding this issue would be appreciated! I know the 
AnalogOutputTask works in other context, so there must be something about this 
simple task that breaks a deeper issue I'm having with calling AnalogOutputTask.

Thanks,
Andrew
