The first thing I'd like to mention is that this plugin is actually owned and maintained by Katz Web Services, who is one of our partners. I do happen to know a bit about the plugin due to having worked with it, but we are unfortunately unable to make any changes to plugin.
Part of how this plugin authorizes is that it attempts to pass information needed to connect back to your wordpress install. What's the domain and path for your install? It sounds like there might be a bug in how the plugin authorizes that may be something specific to your wordpress installation. Would you be able to share the URL for your wordpress page?
