Looks like first thing to do would be to look at versions for the driver installed and updates and perhaps a reinstallation.

Hello Mado,

did you manage to resolve your issue? It seems I have the exactly the same one. My drivers are up to date but I still get the same error. If you have an idea why the error appears it will be of great help.

I am using Windows 10, 64-bit and installed the latest drivers from NI (v15.x). The device appears to work properly from the device manager.

Many thanks

Andreas
