Map Not Rendering

I am attempting to render a map I have recently downloaded that is so big I need a world map to see all there is to see. I watched all the video tutorials and did everything that was explained correctly. I provided the png, I provided the zip file by doing the same steps shown in the tutorial, and when all was done, I clicked save and went to view my map only to find a white expanse of nothing. I'm on a windows 10 computer if that's of any importance. I attempted several re-uploads and went through the troubleshooting solutions provided in the 'Help my map isn't rendering!' thread. As far as I can tell based on all the tutorials and solutions I've looked at, the map should be working. The link to my map is

If there is anything that I have not done correctly or anything that anyone can find that can fix this issue please respond. 

Thankyou,
