OpenRefine 3.7.9 released

I can see my projects, but when I open them they are unusable - this is my view! Same in Firefox and Chrome. One row visible, no data showing for that row. I can filter on a row and it comes up with correct number but will never actually stop showing the 'working' popup. And although I deleted the schema that was there, it has somehow computed hundreds of thousands of errors Completely broken (and if I go back to a previous install, the files are still borked).
