Plugin Unsupported now? Templates not working

Just looking there are 3 posts here which are unanswered in more than a month! I’ve just paid for the extra lens’s and templates but the templates are not found by the plugin. Youtube ID is not found by the plugin either. Has the developer forgotten about this plugin?
Please tell me why the templates are not found by the plugin. I have installed 12 and they appear to have installed correctly but I can’t use them.
