Closure files not working

I'm trying to run Santa Tracker on my Windows 10 computer. I've fixed some errors, and everything's working except for the closure.js files on each scene, so I can't fully access scenes. Other virtual files work fine. Closure files just give 404 errors with no other logs. I tried to fix it with no success. Any idea of why does this happen?

(Sorry for all the edits, I thought config.json wasn't working but then I checked again and it did work, that's why I edited the title 3 times)
