LabVIEW Control Design and Simulation Module version 2013

[ejt41]

I have had Labview downloaded for quite some time now. Downloaded control design and simulation module. Installed it. When i go to use it in the
functions menu, only the window appears. Opening it shows an empty window. I have attached a screenshot of the issue. Could someone please explain to me what the problem is and how I can go about fixing it?

Is the suite correctly activated? (Maybe the evalution period has expired)

As Altenback said, It is very possible it expired or it needs activation. To see for sure, go to your "NI License Manager" and expand the Modules. you should see:

If not green then you have to fix the license.
