I can not get this to work. Tried with both Firefox and Chrome, and turning of the add blocker. I just get the "Entering world..." popup that just stays there.

I can not get this to work. Tried with both Firefox and Chrome, and turning of the add blocker. I just get the "Entering world..." popup that just stays there. Occasionally I get the red popup with cryptic "World is clean" message. I tried registering, I tried different worlds, even tried it on my phone, but it just doesn't start.... :(
