Problems with task

[CMG Electrónica]

Hello, I am programming a signals generator in LabView 7.0 with a DAQ NI USB 6009, everything is ok, but Labview is showing error 200428 due to the task.

This show me a messenge because the task has not been created or has mistakes..To create the task, before, I clic in Tools---NI-DAQmx Base Task Configuration Utility, " create new task " then I place " analogical exit " "analog output". Then I select the channel AO0 and other one in none, save and exit. Then start LabView, open my program and run with the error 200428...

Do I need to form something in the Measurement & Automation before? 

Here I attach the .vi in order that they could help me. Thank you!

Since you are using DAQmx functions on the block diagram, you should not be using DAQmx Base configuration. I don't quite understand why you even have that option. Yes, you need to create the task in MAX and under 'Data Neighborhood>NI-DAQmx Tasks'.

You might want to uninstall DAQmx Base in order to avoid further confusion.
