So, I take it you did perform the steps? You only need to - in fact you only can - do it once, it's not really possible to undo it, but it shouldn't be necessary either (don't worry, it doesn't do anything serious to your system, it just copies some files to /var somewhere).
Are you trying to tunnel the X connection to a different computer, that is, even if you run the software on the licensed machine, are you connecting to it via SSH, and trying to run VNL this way? That is also not possible, you really need to sit at the physical machine and run it there (as things are right now, with your current node-locked license).
