I am trying to load the Luxury Hotel & Spa demo but it is not loading. What happens is that it gets about 30% or so loaded and then starts over at zero again and keeps repeating that process. 

I believe the issue could be that the importer is loading on an insecure network (HTTP) while we are on secure one (HTTPS). This is the error: Mixed Content: The page at 'https://lakemiluxuryrentals.wpcomstaging.com/wp-admin/admin.php?page=thegem-importer' was loaded over HTTPS, but requested an insecure image 'http://democontent.codex-themes.com/sites-democontent/luxury-hotel-01/screenshot.jpg'. This content should also be served over HTTPS.

Where would I find a  WXML file that I could use? I didn't see one in the zip file.
