I'm trying to open ethereum studio, but the tab closes a second after it opens. I've tried opening it through both chrome and edge.
I was having the same problem, and had to dig around for quite some time before I managed to find an answer, which I'll post here in case anybody else comes looking.
Basically, the project has been discontinued, so no more ethereum studio, even if he ether camp website is still up and running. Not even invites to the slack channel are working.
There's a reddit thread on it here: https://www.reddit.com/r/ethereum/comments/6c23ua/is_hack_ethercamp_dead/dhrf0aa/
So for anybody looking, you'll have to find another IDE. Sorry.
