I actually just got Chrome working, after sitting on the screen for a while it eventually popped up.
Although testing Firefox that one is still stuck. It loads up everything but then gets stuck on a black screen with the version number on the bottom right.
EDIT: Nevermind, after refreshing the page on Chrome it won't load again. It's stuck as you said, on the load screen with an empty bar with the hearts. After a few refreshes it started to work, but it got stuck on an endless loop on the unpacking data load screen.
