Thanks again for persevering and sorry for the problems.
The console error I have seen and thought was fixed, but others have I think hit too: see over on the (separate) developer forum. I may have lost a fix when I rebased to 0.12.2-pre which is what this uses, but you should still be able to get it going 
if you refresh and click the snowflake a few times you might be lucky. Also helps if you cross your fingers
