"2/3 | Connecting" error

Hi!
I was just in the x3D Design when the site crahshed for me. Since then I can't get into the app again, doesn't matter if I try loading an older design nor starting with a new one. It starts to load but can't seem to get past "2/3 | Connecting". I've tried to restart the computer but still no success.
