Is this Plugin Abandoned or still Active?

Perhaps the lack of response answers your question? I’ve been using this plugin on one of my customer sites since 2014. Originally it was purchased and there was support offered. Seems that it has been abandoned. If you go to the usability dynamics, or the UDX website there are no links to the plugin. There are some old support pages that some links in a Google search bring you to, but things seem to be pretty broken from my perspective.
