World download not working.

Hi all! My aternos world download is not working.

I have looked around on the forums and have not found a solution. I'm using chrome canary and I have tried downloading in an incognito window, none of it works. I left the window open all night in case it needed time, no luck. So, what happens is when I click the button, the gear spins for a bit and then turns to a tick, after that my cursor turns into a spinning state (not a beachball, the one with cursor and the spinning blue and light blue ball), the cursor returns back to normal and nothing happens.

If there is not a solution and an admin is able to download it for me, that would be great but I ask you to not download it yet, I need it on the 15th of June, since this is a school project.

Thanks everyone!

Sorry for replying lots here, but I imported it into my minecraft and realised that it was my progress from a couple of days ago... I started up aternos and all my progress was still there, it's only the file I downloaded...

Is there a fix?

Thanks for your help!
