Install the latest version of DNN Livesupport found here:

The first Error, I came across was that the v.5 license did not work, so I was given a v4 license key to get this functioning.
Log into your client side application.
On your DNN site add a desktop module.
Click on the picture in that module.
That is where I get the error. I had tried this before and everything worked properly, but this time I am getting the error being thrown.
