Xtreme TreeView 16.4 error in VS.NEt 2013

   I have a treeview inside a VB.NET form, however, as soon as the form is closed and the Main() methods finishes I get the following exception:

COM object that has been separated from its underlying RCW cannot be used

If the treeview.nodes.Add() method is executed (to add nodes) the exception is thrown. If I Comment out that single line, the exception is not thrown.

Any idea?

There's no source code. The entire exception says:

A first chance exception of type 'System.Runtime.InteropServices.InvalidComObjectException' occurred in Unknown Module.
