Out of interest, how many of you with problems were using the free viewer? I've just updated it to use a https link, so hopefully this resolves the issues. The free viewer wasn't using https, but the 2D viewer was.
Sorry you are still having to live with Java on the live site; we're working flat-out to finish the new game and bring you the new WebGL viewer, which we have been using on the closed beta for nearly two weeks now.
Testing is going well, and the update is coming soon. You won't have to put up with this Java mess for much longer!
The sooner the better jack, glad to hear the testing is going well
