SSD Toolbox throws unhandled exception "Object reference not set to an instance of an object."

Hello,

When launching the Intell SSD toolbox (I have tired both 3.5.2 and 3.5.1 versions) and unhandled exception error is thrown.

-----------

System.NullReferenceException: Object reference not set to an instance of an object.

   at controls.Button_Drive.get_Drive()

   at gui.MainForm.Stopped(Object sender)

   at Interfaces.StoppedHandler.Invoke(Object sender)

   at Interfaces.IFeature.OnStopped()

   at ManagedTDK.SystemTuner.runWorkerCompleted(Object sender, RunWorkerCompletedEventArgs e)

   at System.ComponentModel.BackgroundWorker.OnRunWorkerCompleted(RunWorkerCompletedEventArgs e)

   at System.ComponentModel.BackgroundWorker.AsyncOperationCompleted(Object arg)

------------

System is Windows 10, 32 bit, running on an Intel Atom Z3740 processor.

The drive in am attempting to analyze (because it is not working) is an Intel SSD 520 Series 480GB (attached as an external USB drive).

I have googled for others having the same problem but found zilch....

Any help is appreciated.  Thanks
