Took a look at the files from the 3 packages, in the most recent, most of the uistate files are dead .. (full of NULLNULL etc) and in objects quite a few of the same cases with the json files. Sadly, some of those json files (from objects) do no exist in the former back ups ....
In all honsty ... looks like a lost cause trying to "retrieve" the events and states.
From here, personally, I'd dive straight in and rebuild in a new file ....
