Getting the same thing here - was working about 45 minutes ago before I left work, got home to finish off some missions and getting the "Sorry, the loading didn't work." error
This is happening to me as well. Kind of annoying since I have the most time to play at night before work.
Same problem here, as well. Put in a ticket, since other Nutaku games are working fine.
Im experiencing the same problem as well. Tried clearing cache and even tried using a different browser. No change
Interestingly enough, game is working when it thinks you are using a mobile browser. tested on phone, then faked chrome into pretending it is android internet, both loaded.
the browser emulation change works - I'm back in and can continue my quests that way
