Visualizer connectivity

I am trying to pick a visualizer to purchase for use with Hog4 PC. I was running V2.4 and had Capture Argo student edition running just fine. In looking for another option, I came across Hog version 3.3 so I downloaded and installed that. I am now unable to connect with the Capture Argo. The 'Hog Visualizer' box that used to pop up when I launched Capture Argo no longer opens.

I also downloaded a trial version of 'Realizzer' virtualization software but it cannot connect to Hog either. Does this new version of Hog (3.3) require that a USB widget be plugged in in order to enable ArtNet? I didn't use one before as I was using my home machine to do these trials.

Hopefully it is ok to ask here in the forum instead of the support site? How do I get connected to Realizzer from Hog4 PC v3.3? I sent an e-mail to Realizzer and they informed me that there is no limitation on connectivity when using their trial version.
