I don’t know, at this point, what version it was before I updated it, but at this point it’s the latest, pro/premium version of the plugin.
I don’t know how to answer these other questions.
I was not involved in the initial installation, configuration, or implementation of this plugin, but was just asked to try to fix it, now that it isn’t working.
I have all the xml/json/php exported files, if any of that will help.
