My Server's Fileserver

So yeah, the title explains the topic. The fileserver that holds my server has been down for a couple weeks. I have heard that reinstalling the server works, BUT there is a slight problem. A few friends and I have been working on a map for a future Pixelmon server. I can't start the server so we can work on it, and I can't download it. I have a VERY early build of the map, where there's barely anything compared to what there is now in my singleplayer worlds, but it would take far too long to redo what was built since I uploaded the world to Aternos. So, I was wondering if the fileserver will be back up anytime soon, and if not, if it can be moved into a working file server without losing the world. If it helps, my static ip is freezinater.aternos.me.

Ok, so I did that, and thankfully the map is fully intact, but now my server keeps stopping even though all slots are full. Any help there?

It was just randomly stopping, but I didn't check console, but whatever it was, it seems to have fixed itself now.
