Import Double Array from File - Error

[nsimo]

Hello, I'm using Veristand 2013 SP1 and would like to import a double array from a file in order to play it with PlayWaveform.nivsseq. When I right-click on Local Variables / Import Double Array from File, I get the following:

An error occurred:

The invocation of the constructor on type 'NationalInstruments.UI.WindowsForms.WaveformGraph' that matches the specified binding constraints threw an exception.

Details

System.Windows.Markup.XamlParseException: The invocation of the constructor on type 'NationalInstruments.UI.WindowsForms.WaveformGraph' that matches the specified binding constraints threw an exception. ---> System.ComponentModel.LicenseException: NationalInstruments.UI.WindowsForms.WaveformGraph evaluation period has expired.

Q1: What the error message above means?

Q2: Is it the best way to play a custom waveform in Veristand or is there another way?

Thank you!

Hello,

I guess the key point in the message is: "System.ComponentModel.LicenseException: NationalInstruments.UI.WindowsForms.WaveformGraph evaluation period has expired."

So you may have a licensing problem on your computer, maybe you need just to reactive it.

Best regards
