Nice looking, doesn’t work with latest wordpress

It just doesn’t work. Looks great, love the interface but it won’t let me add any elements once it’s created, just freezes. In all browsers. Tried the support page but that didn’t work either. Get it to work and I’ll give you 5 stars.

It does work in the older version of wordpress but we are not moving back in time for a plugin. Looks to be not supported anymore.
