Unable to connect Hog4PC to Capture Argo

Hello,
Since 3.2.1, we are not able to connect our Capture Argo with Hog4PC. Capture doesn't show any external universe as before. Also, we found that the connectivity windows does not appear anymore. We checked everything we know, like the connectivity on the open window, the IP address, etc. Please help as we need to pre-program a show this week, and nothing's working right now!
